RE: CPU running at 100%, GUI locks up

It is possible that on that set of hardware a GUI operation is trying to happen before the App has finished initialising - the print statement will slow down the code enough that the initialisation has time to complete. You can try to isolate this by moving print statements a few lines (first try removing/commenting them to see if you get back the problem). It sounds like you might have a candidate for a CallAfter.

Subject: RE: [wxPython-users] CPU running at 100%, GUI locks up

I tried running the debugger using "gdb  python xxx.py", but that didn't work (gdb complained that my python script was not a good core dump...), so I went back to the good old method of inserting "print(...)" statements. The interesting thing is that now the problem does not occur anymore. I guess the execution of the "print(...)" statements somehow changed the code such that it does not run into the problem anymore. Hmmm.
