Thank you both for the suggestions. I have tried several combinations. After installing allfonts and sticking with dotnet20, the debug is at its "best". > fixme:powrprof:DllMain (0x7e5f0000, 1, (nil)) not fully implemented > fixme:ntdll:NtPowerInformation Unimplemented NtPowerInformation action: 16 > fixme:ole:CoGetContextToken stub > fixme:shell:URL_ParseUrl failed to parse L"System" > fixme:shell:URL_ParseUrl failed to parse L"System.Windows.Forms" > fixme:shell:URL_ParseUrl failed to parse L"System.Drawing" > fixme:shell:URL_ParseUrl failed to parse L"System.Configuration" > fixme:shell:URL_ParseUrl failed to parse L"System.Xml" > fixme:win:EnumDisplayDevicesW ((null),0,0x32dd34,0x00000000), stub! > fixme:win:EnumDisplayDevicesW ((null),0,0x32dd34,0x00000000), stub! > fixme:exec:SHELL_execute flags ignored: 0x00000100 > fixme:ntdll:NtPowerInformation Unimplemented NtPowerInformation action: 16 > fixme:powrprof:DllMain (0x7e5f0000, 0, 0x1) not fully implemented I tried both versions of mono available and unfortunately, the crashes were worse and roughly the same. If somebody REALLY wants to know, I can provide screenshots or something. When running this app in Winblows, it docks itself at the bottom or top of your screen. Does the debug/crash info look to you like it is having a problem with that? I tried telling wine to emulate a virtual desktop in hopes that it would make a difference but it didn't...
