Vista Quick Launch Toolbar (or not)

I'm running Windows Vista Ultimate with all updates

When my computer comes back from sleep (powersaver) mode the quick launch bar disappears. Also, after it disappears any window that I minimize disappears.

The file "users/microsoft/internet explorer/quick launch" exists and has a program list in it.

The Quick Launch box on the toolbar menu is checked.

When I reboot the computer the Quick Launch toolbar reappears.

Does anyone have a suggestion? I would really appreciate some help on this one.
