Pointer problem

[MysteryHat]

I just noticed after this update, that as I'm using my Macbook, my pointer will, just for a split second, change a part of the screen behind it to black. Its a really strange problem, and its getting a bit annoying. The part changed to black is about an inch by an inch, and happens extremely quickly. It actually took me about 5 minutes to figure out what it was actually doing. Anyone else having a similar problem or have a solution?

Thanks

Are you running any applications when this happens?

Usually it occurs while I'm using Firefox, but I've noticed it happens with any application where there is alot of text.

I think I have the same thing.

The black spot for me isn't that big, it's about a quarter inch and just looks like the mouse turns into a black blob. On the Apple website there is a thread about it too. I think it may have something to do with the Black Beach Ball that Mozilla uses (like Mac's colored one) but I am really not sure because like you said, it is so fast that I can hardly make it out. But I agree that it is getting pretty annoying. Does anyone know anything?
