Fixed that. No errors yet.

In my function (in the second module), the loops runs in a "try:" and I
added the following exception:
except QuitThread == 1:
thread.exit()
Now, it crashes with the following error message
NameError: global name 'QuitThread' is not defined
and it points to the above exception as the source of the error. This is
strange, since QuitThread is definitely defined as a global variable in
the main module.

By the way, it *doesn't* crash when I comment out the "print QuitThread"
line inside the loop.
Thanks for you help,
Amit.
