Are you sure you didn’t make a typo? I don’t know if you copy&pasted the environment variable or just typed it in, but if it is the first, it should be PYTHONPATH, you forgot an H…
But then again, I have heard others having the same problems nevertheless…
Also, I don’t have a full python2.1 install, but I don’t think tools/idle should necessarily be in your path, and I don’t have a plat-win directory either, it probably should be something like this:
SET PYTHONPATH=C:\PYTHON21;C:\PYTHON21\DLLS;C:\PYTHON21\LIB;C:\PYTHON21\LIB\LIB-TK
At least, works for me (also Win98)
edit:
Just saw everything’s ok now, oh well, I hope this is useful to someone else then…
