Why does my program work with the extension .py, but not with the extension .pyw?

Question

I have a script that converts Google Earth .kml/ .kmzfiles to shapefiles using a simple GUI written in Tkinter.

My problem is that it works fine with the extension .py, but when saving with the extension, .pywit stops when reading my files .kml.

There are no error messages and this is not a failure. The GUI starts normally, etc., but it just stops and is always in about the same place. I am using Python 2.5 and had the same results with Python 2.7.

Any ideas what might cause this?
