I've followed the inscructions and both manually created a script and installed winetricks and done "$ sh winetricks nocrashdialog".
But the crash dialog still appears when I am launching Warcraft 3 with iCCup.
Crashdialog appears even though precautions are made
Re: Crashdialog appears even though precautions are made
I can confirm this. For some unknown reason the DWORD ShowCrashDialog in HKEY_CURRENT_USER\Software\Wine\WineDbg is flipping from 0 to 1 "by itself".
