I found out that installing the LiteStep alternative for windows taskbar actually has the sideeffect of disabling the windows key... (But I don't know how inclined you are to tinker with your system to that degree. At least it offers a clean uninstall)
winKey+e still works after installing LiteStep. Don't have a working URL at hand so try googling for it... But a direct solution for your problem, no I don't have that. cheers, --Tim -- http://mail.python.org/mailman/listinfo/python-list
