Code: =>1 0x7e16f3cf X11DRV_GetAsyncKeyState+0x4f(key=1953724755) [/home/speng/wine-1.1.9/dlls/winex11.drv/keyboard.c:1852] in winex11 (0x7befe6cc) 2 0x7eba4d91 GetAsyncKeyState+0x21(nKey=1953724755) [/home/speng/wine-1.1.9/dlls/user32/input.c:276] in user32 (0x7befe6dc) 3 0x00456347 in shadowflare (+0x56347) (0x00000000) Looks like bug in that program. 1953724755 is not a valid key. The question is, should Wine cap that to < 256 or not? Please open a bug report in Wine's bugzilla and attach terminal output as a text file. This needs a test case.
