When did the problem started? What programs do you instal close and before the problem starts?? Is your WLM patched with A-Patch, Mess Patch or anything else like they)?
Don't forget to tell us your version of Windows Live Messenger (going on Help >>> About)
Suggestion: Have you sent Microsoft's the report?? Because sometimes, after the report, in the window saying that the report was sent, there is a link for more help to solve the problem...
