--- Comment #4 from P Maloney patm@ait.cx --- Thanks! Yes, with that patch on 9.14, strwinclt.exe does not crash when clicking Options / Advanced. I am then able to set the correct graphics options for Wine and bring up the entire Splashtop RMM application. It works perfectly.
As Andrew correctly noted, TrueType fonts are required. Installing corefonts resolves that problem, or installing msttcorefonts as my build script does.
