I am not a eric4/qt specialist - but for me it looks that eric4 spawns new 
processes (which can be placed by kernel in other cpu/core).

Anyway - I read that you are using Vista + Eric4.

Is this combination works ok for you?

Which python/QT are you using?

I've problem with Eric4 that after run it - it sometimes run, sometimes not).
