--- Comment #4 from Mikolaj Zalewski mikolaj.zalewski@gmail.com 2008-07-05 17:13:59 --- After downloading Examdiff Pro 4.0, I can confirm this bug. It is caused by COMBOEX_GetText returing NULL in COMBOEX_GetListboxText. Later we do an lstrcpy and lstrlen which, on Wine, don't have exception handlers. I will have to check where the bug is.
