Code review please - script never ends

[JonPedder]

Not sure how else to say it, but after running the code below, the processing window just flashes continually and the script doesn't ever appear to end. I have to kill ArcMap process to get out of the script.

I'm posting my entire code snippet below, hopefully someone can point out my error.

Warning, new Python coder here, please don't laugh "too hard' at my brute force coding attempts 😛

And here's my parameters code in case the bug lies here

from arcpy import env

  the behavior of the tool's dialog."""

    called when the tool is opened."""
    
    
    subjects = []
    fc = "PLS_Subject_Information"
    field = "Name"
    cursor = arcpy.SearchCursor(fc)
    
    for i in cursor:
      sName = i.getValue(field)
      subjects.append(sName)

    self.params[6].filter.list = subjects
    self.params[6].value = subjects[0]

    return

Update: This is happening with all my scripts so isn't code dependent. I've re installed SP1 for 10.1

Next is to see if the DB or mxd is corrupt

Ok I think all this was a corrupt MXD file, interesting.
