Hi Sherman,
What kind of docklets do you have on your dock? I'd recommend heading into the Advanced Options and choosing the options to temporarily disable docklets. Reload ObjectDock and see if it still takes a while. If not, then there’s a good chance one of the docklets you're running is slowing it down. I've found "SysStats" docklets tend to do this...memory meters/cpu meters that kindof thing.
If that doesn't do it, I'd try temporarily turning off system tray functionality, and perhaps taskbar functionality, to see if either of those are the culprit, just for the sake of having a better idea in case something is wrong there that we need to fix. Less likely than the docklet scenario, but worth checking out.
Let us know how it goes - thanks!
Best Regards,
