Hi all,I have written a script that finds all the mxds in a directory tree and creates a new shapefile with their extents as features. It works pretty well until python keeps crashing. This is driving me crazy, as it isn't an error as such, just a straight "python has stopped working".If anybody could try this out, or let me know if they can find any issues with it that would be great.One other problem is that sometimes the code fails as python cannot add the fields to the index featureclass, it says it doesn't exist, even though it has literally just been created.Please excuse my beginners coding...## This script is written to recursively search through a directory, find all the MXD files and create a polygon
## shapefile with a feature showing the extent of each dataframe. The features have several attributes related
## to the dataframe extents.
