Wait, never mind, dwmapi is not in the stack trace, so I guess it works well enough for now. I guess that program is calling another (apparently undocumented) function in user32. An undocumented function that probably wasn't present in windows XP, even. The program claims to work on Windows 2000, so it shouldn't really need such new api's. Here's a thought: Instead of setting dwmapi to native, set it to disabled and remove .wine/drive_c/windows/system32/dwmapi.dll. -- Vincent Povirk
