Are you running QTTabber?
No, not running QTTabber.
Fly-out or normal?
Normal objects, not flyouts.
ObjectDock is running with no problems on my laptop (XP, slower proc, 2GB RAM), but there is another difference: my desktop is running WindowBlinds (installed with Object Desktop), and the laptop is not.
Also, I failed to mention this: for one day about a week ago, ObjectDock was opening those same special folders (My Computer, My Pictures, UNC network links, etc.) quickly with no delay. I don't recall what I had done surrounding that event (software install/uninstall... reboot...), but OD worked OK for a brief time.
These links all work from built-in Windows locations like the Quick Launch bar, Start Menu, and desktop. Why not OD? Arrrrrrgh.
