Tk() doesn't bring up a window in Python2.4

[timothy.williams]

Hello.

I recently installed Python2.4 on both Linux (Redhat FC3) and Windows
XP. The build and installed went fine as far as I could tell. I
Windows, when I bring up IDLE, or pythonwin, I can't bring up a new
Frame widget with Tk().

If I use idle from a DOS window, everything's fine. Python programs I
have that use Tkinter also work from either IDLE.

Thanks for any help.
