Win GUI application: avoiding DOS console

[Siggi]

Hi all,

how do I avoid the DOS console show-up when starting a WinXP GUI application 
with mouseclick on the respective Python file?

I had this with my previous Python installation; it is very simple, 
something with a "-i" somewhere in the open command of the  MS Windows data 
types "PY" and "PYW". But after a new Python installation, this was lost, 
and I cannot find the instruction what to do.

Please help!

Thanks,

siggi
