I seem to be frequently running into a situation where I have 9,999 GDI Objects for ParallelsToolsCenter.exe build 3214. (As viewed in an optional Task Manager column.) Things get sluggish and strange when this situation occurs. (The next largest task using GDI objects is 936 right now...) There must be some GDI Object leak. Killing and restarting ParallelsToolsCenter.exe gives it 265 GDI Objects. I've had to restart it 4 or 5 times since I upgraded to 3214. After restarting ParallelsToolsCenter.exe, my clock got all out of sync with the Mac clock... but otherwise killing and restarting hasn't been too problematic.
