    WIN-PROLOG 4.700

    The following updates are available for WIN-PROLOG 4.700 and its toolkits:
    ProductDescription
    VisiRule for WIN-PROLOG 4.700 A number of performance issues have been addressed and a several minor bugs have been fixed since the 4.7 release of VisiRule: these have been collected together into this update. In addition, a convenient shortcut file has been added to simplify the process of starting a VisiRule session.

    This update contains three files: two are direct replacements for VISIRULE.PC and VRLIB.PC, and a third, VISIRULE.EXE, is the new shortcut. No other issues are addressed by this update.

    WIN-PROLOG 4.500

    The following updates are available for WIN-PROLOG 4.500 and its toolkits:
    ProductDescription
    WIN-PROLOG 4.500 Three behavioural problems with the Change, Find and Progress Box dialogs were discovered in the release code, and have been fixed in this update. Global search and/or replace now work correctly in the first two dialogs, and long computations can now be aborted by clicking the "Cancel" button in the latter dialog.

    This update consists of a single file, PATCH.PC, which should be loaded into WIN-PROLOG and executed using the predicate, patch/0. No other issues are addressed by this update.

    WIN-PROLOG 4.322

    The following updates are available for WIN-PROLOG 4.322 and its toolkits:
    ProductDescription
    Data Mining Toolkit 4.322 A problem has been found in the Data Mining Toolkit (DATAMITE\DM_API.PC), whereby a database can be successfully connected to, but sometimes cannot be called. This only affects those people using the Data Mining Toolkit.

    This update consists of a single system file, DM_API.PC, which should be used to replace the copy that came with WIN-PROLOG 4.322. No other issues are addressed by this update.

    flex Toolkit 4.322 Two problems have been noticed in the "Flex/Analyse Syntax Errors" menu option. The first is an unwanted interaction with certain settings of the Prolog flag, "print_message", and the second is the delayed updating of the checkmark (tick) after clicking this menu option.

    This update consists of a three system files, FLEX.PC, FLEXDLG.PC and FLEXENV.PC_API.PC, which should be used to replace the copies that came with WIN-PROLOG 4.322. No other issues are addressed by this update.

    WIN-PROLOG 4.321

    The following updates are available for WIN-PROLOG 4.321 and its toolkits:
    ProductDescription
    WIN-PROLOG 4.321 A month or so after release, it was reported that the Call Graph utility module (SYSTEM\CALLGRAF.PC) was causing a problem with application generation, whereby the resulting overlay (.OVL) file would fail to load.

    This update consists of a single system file, CALLGRAF.PC, which should be used to replace the copy that came with WIN-PROLOG 4.321. No other issues are addressed by this update.

    WIN-PROLOG 4.320

    The following updates are available for WIN-PROLOG 4.320 and its toolkits:
    ProductDescription
    WIN-PROLOG 4.320 Shortly after going into production, it was noticed that the Call Graph utility module (SYSTEM\CALLGRAF.PC) was causing a major performance hit in WIN-PROLOG 4.320's menu handling, making the overall responsiveness of the system noticeably slow compared with previous versions.

    This update consists of a single system file, CALLGRAF.PC, which should be used to replace the copy that came with WIN-PROLOG 4.320. No other issues are addressed by this update.

    Intelligence Server 4.320 As shipped, the Intelligence Server Overlay (INT386W.OVL) is being corrupted during the WIN-PROLOG setup program. This sometimes causes Intelligence Server applications to fail or hang at startup.

    This update consists of a single system file, INT386W.OVL, which should be used to replace the copy that came with WIN-PROLOG 4.320. No other issues are addressed by this update.

    WIN-PROLOG 4.300

    There are no updates for WIN-PROLOG 4.300 or its toolkits

    WIN-PROLOG 4.200

    The following updates are available for WIN-PROLOG 4.200 and its toolkits:
    ProductDescription
    WIN-PROLOG 4.200 The wfind/3 predicate in version 4.200 of WIN-PROLOG, build 4.217, does not work correctly, resulting in an "Instantiation Error" whenever called.

    This file patches the 4.217 build to level 4.218, fixing this problem. No other issues are addressed by this patch.

    You can tell which build you are currently using by checking in the "About Box" (Help/About). The fourth line of text in build 4.217 reports:

      "System 4.217 created 24 Oct 2001"

    If you system has any other build level, then this patch is not applicable.
    Intelligence Server 4.200 When an Intelligence Server application is run from a directory that is not the current working directory, or where one or more copies of PRO386W.EXE exist on the PATH, the application may fail to load correctly. Exact symptoms vary, but the workaround so far has been to ensure that all necessary files are placed early on the PATH.

    This file contains modified copies of the file, INT386W.DLL, which overcome such problems by loading PRO386W.EXE directory from the same directory as the DLL file, rather than searching for it on the PATH.

    There are three versions of INT386W.DLL in this patch, one for C/C++/Delphi, another for Java, and a third for Visual Basic.

    If you do not use the Intelligence Server, then this patch is not applicable.


    WIN-PROLOG 4.110

    The following updates are available for WIN-PROLOG 4.110 and its toolkits:
    ProductDescription
    WIN-PROLOG 4.110 Programmer Edition Shortly after releasing version 4.110 of WIN-PROLOG, an issue was discovered with respect to the recognising "Programmer Edition" keycodes. The symptoms are that the software sometimes reports, incorrectly, "Sorry, your evaluation has expired". This problem does not affect the "Developer Edition", or true evaluation copies.

    This file patches the 4.111 build to level 4.112, fixing this problem. No other issues are addressed by this patch, so you only need to apply it if you are using the Programmer Edition.

    You can tell which build you are currently using by checking in the "About Box" (Help/About). The fourth line of text in build 4.111 reports:

      "System 4.111 created 14 Jun 2001"

    If you system has any other build level, then this patch is not applicable.

    WIN-PROLOG 4.040

    The following updates are available for WIN-PROLOG 4.040 and its toolkits:
    ProductDescription
    WIN-PROLOG 4.040 This patch fixes a problem which causes the "Find" and "Change" dialogs to highlight the "Selected Text" button after finding some text, preventing a second or subsequent match
