SystemUIserver using 90+% of CPU

I was browsing the web, minding my own business... when I noticed the fans were running high.
Thinking it was Flash, I closed Firefox. But the fans were still running at max.

Popped open Activity Monitor - and SystemUIServer was running 80-95% of my CPU, and Dock was using a fair bit too.

Reboot did nothing. Ran a set of clean-up tools through Cocktail, as well as repairing of permissions. Nothing still.

Can't explain what's going on. I haven't changed anything, not doing anything... and SystemUIServer is hogging the CPU.

Vista was not THAT bad, it was just too different from the XP, and was trying to introduce too many new things and address too many issues at once. Vista was an enormous step for Microsoft.

Snow Leopard, on the other hand, was supposed to be a more polished version of Leopard. What it turned out to be is a mostly broken version of Leopard.

My personal opinion is that so far the only decent version of Mac OS X was the Tiger - they've fixed most issues there, which then reappeared in Leopard, and successfully made it into Snow Leopard. I personally have a few bugs reported that are nearly 3 years old now, with no fix in sight. I already have Windows 7 installed on my MBP, so it's just a matter of time before I'm forced to switch away from OSX, seeing as to where Apple is heading... It indeed used to be "It just works" with Apple awhile ago. Now it's mostly "It just doesn't".
