I always thought it had something to do with my harddrives having to get revved up. For example, if I step away from my computer for 10-15 mins, then come back and instantly try to do something, it takes a moment for the harddrives to get spinning again or something. That is usually when AE has it's fit. I make it stop by clicking the AE logo on the taskbar a few times.

And now we are all glad, it's not just us. Mine also continues and my driver is up to date as well. Oddly it has occurred just yet but the symptoms are exactly as Greg describes. No clicking outside does anything. In fact, nothing else is available either during the time it does this.
