--- Comment #9 from Andreas Christ andreas.christ@runbox.com --- Thanks a lot for your help!
I built wine with -O0 and ran a debug session with the flags you mentioned. I redirected the output into a file with &> but there were still a few messages which ended up in the console. I am not sure if they are relevant.
The debug log is 17MB (compressed). I will upload it in four parts during the next hour.
PS: Bruno, there was a 32bit version of Semcad X. I no longer have the installer, but I tried to run it in Wine a few years ago. The xy-plots did not work, either.
