Hi,
I've installed SP1 for .NET Framework 1.1 - after instalation, when I ran my app I get: "An unhandled exception of type 'System.NullReferenceException' occurred in Unknown Module". So, I can't see call stack because module is Unknown. What is worse, this error occurs not always, but sometimes...

There were no changes to app code - only difference is SP1 for .NET Framework.

Does someone have encountered similar problem? Please give me some advice or comment.

Thanx in advance.
