I run Diptrace under wine on ubuntu and it has problems.
Don't try and edit the title and sheet setup the program crashes instantly, also adding a table to a schematic will cause a crash.
Diptrace support say its a wine problem because the program runs fine under windows.
so they aren't going to do much. I looked in wine bug list and there is no open tickets for diptrace.
hope this helps
Having said that everything else works for me and I would recommend Diptrace in linux
