TclError is sometimes thrown when closing PyDAT

I have no idea how this happened, and wasn't able to reproduce it, though it had happened before when i checked the mapdata changes (Think it only happened once that time too.) So not sure if this is fixable based on stack trace, or how to narrow it down.

Exception in Tkinter callback
