--- Comment #1 from Juan Lang juan_lang@yahoo.com 2008-09-17 19:36:39 --- It looks as though the app is calling CharLowerBuffA with a static string: wine: Unhandled page fault on write access to 0x7e66a856 at address 0xb7e9122d (thread 0009), starting debugger... and from the backtrace: 3 0x7ea2defe CharLowerBuffA+0x1be(str="Primary Sound Driver", len=20) [/home/david/wine/dlls/user32/lstr.c:319] in user32 (0x0032ee4c)
I'm guessing CharLowerBuffA/W need an exception handler to deal with such buggy apps? A test on Windows is probably needed to confirm.
