If I install Python for S60 after Mobile Web Server, start Mobile Web Server, select Connect I get "Internal Server Error". Reinstallation of Mobile Web Server fixes the problem, but brakes Python installation. I can not even start Python Script Shell. Start ends up with error message:
"Check if components are installed
- Python runtime
- PIPS"

Python reinstall fixes problem, but brakes MWS and so forth...

I checked packages, and it seems that the problem lies in fact that MWS and Python use different versions of PIPS service. MWS installs Symbian OS PIPS 1.03(0), while Python installs Symbian OS PIPS 1.05(2).

I doubt if it needed, but here go firmware info
200.34.36
24-04-2008
RM-244
Nokia E51 (05)

Could you check that issue and may be consider switching to newer version of PIPS package?
