I have written a few custom Python Toolboxes that my office uses.
One of my coworkers has an interesting issue that I cannot replicate on a different machine:
When he runs the tool, ArcGIS Desktop crashes and tries to send an error report. The script does not begin running. This happens when running the script in both ArcCatalog and ArcMap.
Only one of the scripts I have written causes this, others behave normally. The script began causing this behavior recently, it previously worked fine for him.
Is there anything I should check?
Re-installing ArcGIS Desktop seems like the only thing that might fix this problem.
