I had discovered a bug with Quicken 2005 where certain graphics aren't being drawn on screen, depending on whether the application is using W98 or W2k "emulation".
The behavior actually changed (from works in W98 but broken in W2k to works in W2k but broken in W98) at some point in time. After some tedius recompiling and testing (hey, I'm new to wine!) I discovered the behavior swap was due to a CVS commit to dlls\user\misc.c on 29 September 2005.
Something to do with the display name being unicode DISPLAY vs. \.\DISPLAY1 (which seems to be the first display name for Windows).
I just sent a proposed patch to fix this bug, but thought I would also ask on this list to make sure I haven't done anything stupid (which I probably have). Basically, there were several files that declare static constants for a display name - I globally search & replaced all DISPLAY with \.\DISPLAY1 where it seemed to make sense, but hopefully others will have an opinion here.
