I have a 12 year old BC45 compiled 32 bit GUI utility that fails to load on XP and 2003 with a GPF. Worked find under 95, NT, 2000 and didn't expect anything to be different for other OSes. But it was reported this week and looking at our support logs, there were other reports last year on this as well. Testing it on XP and 2003 confirms this. I think it is related to either comctl32.dll, comdlg32...
