.NET threading exception

[osvier]

Does anybody know what this expetion means?

The problem is that I cannot replicate the error on my dev machine.. but the client is still getting the error...

I also tryed to set the JIT debugging, but didn't work.

It is a .NET C# (windows forms) application. Framework 3.5 in Visual Studio 2008

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

It happens whenever you call the Abort() method on a thread. The way .NET provides for you to "stop" threads is by generating the ThreadAbortExce ption
