- 64-bit doesn't work, period: it crashes in malloc in wine with heap corruption warnings aplenty during DLL loading; in windows 7 CreateWindowExW complains about an unregistered window class, yet the RegisterClassW appears to have succeeded and examining the stack in WinDbg indicates the correct class name is being sent (see below)
- 32-bit: it works now, but if I save the class name converted to UTF-16 beforehand, wine indicates that the class name is replaced with the window title, so something there is wrong...
