The problem your experiencing is caused by the fact that Tk's just enough aware of threads to compile, and Win32's fork uses threads, and not truly seperate processes like UNIX. When your application exits, Tk's destruction routines get called. Apparently Tk gets confused with multiple threads, and that causes your problem.

The easiest solution to this problem is to move your Tk stuff to after the code for the child in your program. That is after the if. That should prevent Tk needing to call the destruction routines in the child.

Update: To be more specific, the problem is caused by a Widget (MainWindow) being in exsitence for the child when it exits. A look at the tk source code indicates that the use Tk does not appear to be a problem.
