Context.Undo() error, only on Windows XP machine

Hi,

I have an asynchronous socket and I get the following error ONLY on ONE windows XP machine:

The Undo operation encountered a context that is different from what was applied in the corresponding Set operation.

The Undo operation encountered a context that is different from what was applied in the corresponding Set operation. The possible cause is that a context was Set on the thread and not reverted(undone).   mscorlib       at System.Threading.SynchronizationContextSwitcher.Undo()

   at System.Threading._IOCompletionCallback.PerformIOCompletionCallback(UInt32 errorCode, UInt32 numBytes, NativeOverlapped* pOVERLAP)

A little reading on this, indicates many issues, but the fact the it's only happening only on Windows XP, keeps me from actively changing anything; before having a better understanding.

Any ideas, why this is XP specific?

Thank you Theo
