Pmw problem

[Sam]

Hello,

I have made a new GUI app using a couple of widgets from the Pmw widget
set. I am developing on a Windows 98 box at the moment. The problem is,
when I try to run the app by clicking it's icon, I get the DOS console
flash up with an ImportError saying it can't find the Pmw module. When I
run it in IDLE or open up a DOS console and type "python script.py" it
works fine, it just won't work when I use it's icon. What's the problem
here, and what can I do to solve it?

Thanks,
Sam.
