I am new to Python and in the process of taking the "Python Scripting for Geoprocessing Workflows" online course. I am at Service Pack 3 and this is still an issue. Any time I attempt to run my script (either the one I wrote during the course exercise or the one provided as part of the exercise materials) PythonWin crashes. I can successfully run the script in IDLE, and often have success running it line by line within the Interactive Window of PythonWin, but more often than not the program crashes.
I plan to check out PyScripter now so that I can continue with the course, but wanted to post since I too have this problem and it was not resolved with Service Pack updates.
