>I get the dreaded "program has performed an illegal operation and will be shut down' after I get the foxpro message: "Cannot access selected table' Is this unusual? I attampt to select a file normally in the interactive change event of a listbox when this occurs.

It happens. :)
The table you are referring to could be closed by some reason. Try to put SET STEP ON into your InterActiveChange just before line causing problem and look to DataSession window to make sure what tables are open and where.
