cannot start IDLE in WinXP

[imx]

Hi,

Enviroment: WinXP sp2, python 2.5
problem: click IDLE using shorcut menu or run phthonw.exe directly,
nothing happen! But running python.exe from the command line is fine.

I searched this issue on the net and this forum and tried some
suggestions but with no luck.

Any ideas?

Thanks in advance,
Xiong
