I am running OL 2010 on a Win XP Pro machine and on a Win 7 machine. A few days ago OL started crashing when I select a different folder in OL. It auto restarts but shuts down and sends an error message to MS. the same thing happens on both machines. they both started at the same time. I keep both machines updated from MS update so I wonder if some MS update started the problem. Does anyone know the problem and what is causing it?
