[IronPython] Silverlight code need help (Repost)

[Andrew Evans]

I am having problems with my code. I am not sure how to debug silverlight. I
receive no error messages, but this is what happens. When this app runs it
starts for a second then disappears I am not sure where I am going wrong,
any ideas? Perhaps in the threading?

I am not a C# programmer but I am doing my best to find examples to compare
to so I can translate into python


I would really appreciate any help *Cheers Andrew


Here is the full code hope that's alright :D
