I have a toolbar with about 25 items, mostly just shortcuts to various programs. When I first left click on the toolbar name in the taskbar, it can take 5-10 seconds to display the menu. I've tried to determine which (if just one) item that is causing the slowdown, but am unable to do so. Is there any way to speed this up?

Interestingly, the desktop toolbar, which has many more complex menu items only takes about 1 second to display. While it is figuring out what to display, I don't see any appreciable cpu time (watching with procexplorer) nor do I see any disk i/o, so something must be hung up. Also, I have a similar menu on a much slower laptop, which also takes about the same amount of time for its menu to display - again makes me think it's some sort of timeout hang up.

I also can't suspend or hibernate (neither work) so I have to reboot a lot, which is why this keeps coming up.
