------- Additional Comments From MattFinn@gmail.com 2006-10-08 09:43 ------- This was fixed by foltman's patch "riched20: Handle incorrect calls of window procedure." (http://source.winehq.org/git/?p=wine.git;a=commit;h=6f15b54ade21c2c1cbf5a646...)
I just tested it, and it didn't crash. The ouput shows this when the bad call is made: err:richedit:RichEditANSIWndProc RichEditANSIWndProc called with invalid hWnd (nil) - application bug?
This is in the latest git, or version 0.9.19.
