Known bugs and work arounds in releases of Comwin with build date 12-June-2002 or later. The statistics are out of date. The statistics get updated for all articles in the demonstration version of Comwin, just before a new set-up program is prepared. If you downloaded Comwin from the Internet, you will have seen the build date at the top of the Download page. You can also check it by double clicking on a file called BuildDate.txt in the Comwin directory. If this date is not very recent, you will be missing statistics for all periods after this date. If you run forecasting and purchase recommendations, the system will think that demand for your products suddenly dropped to zero, some time ago, and has not subsequently picked up. It will forecast a continuing drop in demand and probably recommend postponing purchase orders that have not yet been received. Work around 1: Go to the  www.comwin.com/download.html or  www.abrasive.se/download.html page and see if the “date of statistics” is more recent than the build date for your release of Comwin. If so, download it and follow the installation instructions at the end of the  Installation instructions page. Work around 2: Use the statistics update window in Comwin to enter figures for the periods that are missing. Work around 3: Export the Comwin statistics table to a file that you can open with Windows Notepad, to see the layout. Make a program to generate statistics in the same format and import them into Comwin. Alternatively, use the Comwin conversion service and let us generate the files you need to import from a copy of your existing system. See  http://comwin.com/conversion.html for details. The documentation is out of date. Around the time we start programming any new functions into Comwin, and definitely before a beta release is published, we try to update the document at  www.abrasive.se/coming.html with details of what the next beta will contain. After the beta is made available, we update the pages that document the changes, in the beta with the latest build date. It can take a few days for things to move from the “coming” page to the “changes” page. It can take months before the Comwin user manual (that word document in the Comwin directory) is updated. After that, the help text gets updated and then we wonder if the beta is ready to evolve into an official new release of Comwin. Work around. See the latest documentation on the Internet. Purchase recommendations can show empty week 53 or 54 when using weekly statistical periods. If you use weekly statistical periods, and see entries for week 53 or 54 that should not exist, be aware that a lack of statistics in non-existent periods at the end of the year, could lead to too low forecasts early in January. Releases with build dates in December 2002, or later, do not have this problem. It was caused by a bug in a routine to generate forecasts, that was fixed in an earlier build. The invalid records can be removed by telling the system to re-generate forecasts from a period prior to the ones that should not exist. It is not possible to manually add article quantities for newly created articles. Work around 1: Use the import function to add at least one article quantity record for the new articles. The manual maintenance window will work properly then. Work around 2: Install the latest beta release. The problem is fixed in releases with a build date later than September 2002. Installing Comwin to a disk or directory other than the default C:\comwin causes a long period of inactivity (up to 4 minutes), and some menu options not to appear on the menu bar. Work around: Be patient, or go get a cup of coffee. After five minutes everything should be back to normal. It seems that MS-Access needs some time to reattach the program database to the file database when you change the location. If you resize (height matters, not width) a form that contains a subform, e.g. forecast parameters, so that you see only part of the subform, close it and then reopen it, the vertical scroll bar is gone, and you will not be able to see the subform. Even changing the size of the form back does not help. Work around:Make the form high enough so that you should see the sub-form, close it, and reopen it again, or, make it so small that you cannot see any of the sub-form, close it and reopen it. The address book add-in will not load on some systems, because a file called system.mdw is missing. This file exists on systems where MS-Access is installed. We have added it to the Comwin set-up program and releases with build dates in December 2002, or later, should no longer have this problem.
