Cursor problems anyone?

Ok, so I know about the cursor problems that have been plaguing Vista, but since the patch and rollback this afternoon, I seem to be experiencing the same deal with Windows XP. The cursor flicks in and out, and strange boxes appear to follow it as the cursor moves. The only change that's happened to my system between last night when it was working fine and today is the updates. Adding -compatiblecursors 1 to my startup does seem to fix it, but I'm wondering if anyone else is experiencing the same problem?

First things first. With all peripheral problems the first debugging step is:

Did you try rebooting your computer?

I've noticed the same problem on XP aswell, very annoying. Tried updating drivers, rebooting, changing graphics settings all to no avail.

Nvidia 8800GT if that makes any difference running at 1920x1080.

I'm having the mother of all cursor problems since power spectrum on the test server. I use a mac by the way. I can't click on any clickable item, including other users toons and enemy toons. The cursor simply flicks away and ends up over on another part of the screen with an accompanying graphic flicker on the top half of the screen. Imagine trying to enter a door mish? It didn't come over when they put power spec on the main game server but after tonight's patch it's here. Boo hoo, as it makes the game unplayable. Just waiting to see what I get back from my report. Hope they sort it soon as double xp weekend soon. Will have to take drastic measures maybe and install windows!!!! Now don't all shout at me at once, lol.
