I'm currently using the Desktop Toolbar but find that every now and again (like once or twice a week) I'll start up my system and it'll be gone. I put it back and it'll stay there for a few days and then reset again. I tried locking the toolbar which made no difference. I've tried pinning My Computer to the taskbar, but it reverts to Libraries (as does Network Places).

Anyone know why this happens and how to stop it? I've tried Googling, but it hasn't been too productive unfortunately.

Cheers.
