[Eric] Can not run Python scripts and empty Shell - Eric3

Sat Apr 21 09:11:47 BST 2007

Hi,

I'm glad everything works now. However, I am a little bit concerned, that the 
problem cannot be reproduced. It seems to be something odd and related to 
your VMware setup. I have tested and am using eric3 and eric4 with VMware 
with win32 and Linux and have never seen that strangeness. If somebody else 
is observing it, please report back.
