tkinter and tcl problems???

Hi,

I'm currently developing a GUI application in python 2.4.3 using the tkinter interface.
The application is supposed to connect to a userset remote server and present the server parameters and
also enable the user to control the server from a remote location.

The problem is the application crashes with a Windows Access Violation error when it tries to update
the view. This occurs when the server sends it's parameters to the connected client (this application)
or when the user tries to change some parameter (for example the scrollbar or the text of a label).
As far as I can tell this happens at random times and at most every second time some of above happens.

I used Windbg 6.8 to get the following description:

(d6c.658): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.

At first it seemed to be some problem with tkinter and floats so I tried to remove all use of floats in
that part of the my code that called tkinter (for instance "FloatVar()" was changed to "IntVar()")
that I could find which seemed to help some, the problem still exists however (some use of floats and tcl might
still be in the code, I do however want to use floats so I hope there is another way) but only
happens about every 10 or 15 time now when some of the above events is triggered.

If anybody knows anything that might be wrong or know a solution don't hesitate to write it down, I'm quite open for
suggestions and solutions.
