Just in case you hadn't seen this behavior yet I figured I'd mention it. I noticed the other day that when you exit the new beta client for AO, the executable remains in memory and they begin to pile up. When you encounter stability issues check the task manager to see how many executables are still present in memory and clear out the stray processes. Maybe there is a correlation? For me the correlation was crappy performance and when I checked I had 5 other instances running.
