I have a Video 7 VEGA VGA (8-bit) card and an older (bought in 1985) Sysdyne monochrome adapter card. I'm trying to use these to do dual-monitor debugging with TDW. The VGA card has a switch to make it be either the primary or secondary adapter. The Sysdyne card doesn't (I don't know if any monochrome cards have a switch to do this). Anyways, TDW comes up on the monochrome monitor okay, but everything on the color screen comes up in black-and-white. That is, the program I'm debugging comes up in black-and-white. If I move the app's window, the area the window previously covered stays black (the background is not drawn correctly). If I iconize and deiconize the Program Manager, all the icons in it (which were color up until this point) are now black and white. Basically anything that has to be redrawn is redrawn in black and white. Normally I run the VGA card in 740x520 mode (or something like). Now I know TDW says it only supports standard VGA, but it's not clear in the manual if this means you need standard VGA to do single monitor debugging only, or if you also need it for dual monitor. In any event, I tried it both ways, standard & non-standard, and it does the exact same thing both times. I also tried the primary/secondary adapter setting on the VGA card, and that didn't seem to matter either. Other than this problem, the debugging process seems to work fine. I just don't like everything going to black and white. Has anybody else seen this? Am I doing something wrong? Do I need a newer monochrome adapter card (or VGA card)? Thanks for your help.

Everything works perfectly now although VGA performance is somewhat degraded. Barry King bking@ersys.edmonton.ab.ca Edmonton Remote Systems: Serving Northern Alberta since 1982

The "official" answer from Borland as to why TDW doesn't run in other than normal VGA resolution is that there is a bug in WINDEBUG.DLL, which they have licensed from Microsoft. This is the same WINDEBUG.DLL that comes with the SDK. It was reported to MS months ago by beta testers. If I were to speculate (which, in fact, I am going to do), I would say that there won't be a fix (if any) until Windows 3.1 ships. FWIW, I dl'd the updated CVW (CodeView for Windows, for use with single monitors) and it didn't include any DLLs.
