RE: CPU running at 100%, GUI locks up

One "trick" that has worked well for me in the past is to  start from the wxpython demo item that is closest to what I am trying to do at the point of lock-up and try to modify it - step by step into a minimal demonstration of the problem. When doing this one of 3 things tend to happen - 1. I can isolate exactly which addition results in the problem an have something that I can share with others for help, 2. I realise the idiot thing that I was doing and so can fix the problem or 3. As  I add my functionality in the problem never appears until I have recreated my app but with the problem missing.

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

Dear all

I have wxPython GUI application that runs fine on machines I have tested so far, with the exception of one machine. The difference of this machine to the others is that it has an Intel Atom E3930 processor, whereas the others are i5/ i7 or Raspberry Pi ARM machines. On the Atom, the GUI suddenly consumes 100% of the CPU time, and therefore locks up. I have no idea where to look for the issue, or what to check. Does anyone have a hint?

Thanks for any insights!
