I'm wondering if anyone else has noticed this:

For the last few days, I have noticed that the Mouse Pointer on both my PCs (desktop and laptop) exhibits weird behaviour after visiting Geekzone.

Basically, the Mouse Pointer is invisible until you move it, whereupon it reappears as normal, then disappears again once you stop moving it.

I have proved that it is Geekzone to blame by closing IE7 with the "Save all Tabs" option selected.  Then opening IE7 again and selecting each tab in turn.  The Mouse Pointer behaves normally until such time as I selected the Geekzone tab, after which point it exhibits the same strange behaviour in all open tabs under that session of IE7.

Yet, if I open another IE7 session from the Quick Launch bar, the Geekzone page (and all other pages) behave normally.

Any ideas?

P.S. My desktop is using a Logitech mouse driver, whereas my laptop uses a Synaptics Touchpad driver, so the two PCs are not even remotely similar as regards mouse driver software.  Yet both are afflicted in the same manner.  Bizarre...
