My trusty XP SP3 system, fully patched, has started showing a curious problem.

After a restart, the Quicklaunch Toolbar icons all change to random icons.
If I go to the toolbar properties, uncheck "show icons", apply, then rechceck "show icons" they all reappear with the correct icons but in a random order from what I had when I went to Restart.

I have the toolbar locked.

I can now resort the dozen or so icons to their proper places.

The desktop icons don't have this problem, not do any shortcuts under the Start menu.

Any thoughts?
