All Program Menu causes explorer.exe to go to 100% Cpu

[tragib]

Occasionally, when I click the All Programs Menu, explorer.exe goes to
100% cpu usage and the menu doesn't appear until about 20-30 seconds
later. During this time, the taskbar is unresponsive and it seems like
the entire shell is hung. I've went though all the shortcuts in the
menu and verified all of them are valid. Once the menu is displayed,
the problem doesn't exhibit itself until 'something' causes the menu to
refresh.

System:
HP Pavilion Laptop
AMD 1700+ CPU
768 MB of ram
60 GB 7200 RPM HD using UDMA Mode 5 (20 GB free)
XP Pro SP2
Trend Micro Internet Security 2005
SpySweeper4/AdAware

No viruses/trojans/etc are being identified by my scanners.

Any ideas?

The same thing is happening to me and most of the machines in my office. We
are all running Dell GX280 desktops with XP Pro. Some of the machines have
all the windows update and some don't. All are P4 3ghz and above with at
least 1gb of ram. Most are running XP Pro SP1. Only a couple have SP2.
