Photoshop CS5 constantly changing my cursor

Question

Photoshop CS5 is constantly changing my standard Windows cursor from a normal arrow to a very big arrow. This is really driving me nuts, because I have to change that over and over again. No other program does this. BTW. I`m also using an Intuos 2, if that can have anything to do with it. I`m using Win7 64bit Ultimate.

Answer 1

I've just started having this problem today. The cursor is fine when starting up my computer and using it, but as soon as I use Photoshop, the cursor becomes enlarged. Furthermore, I can't use any of the tools in Photoshop, it's stuck on paint brush! I can click on any of the tools in the toolbox (say, selection box), but the cursor still shows as a paint brush, and it will paint a brush stroke when I drag (mouse or tablet). Quitting Photoshop and the large cursor problem persists until I restart the computer. I can't get any work done until I find a solution.

Photoshop CS5
Intuos 3
There is a option on Windows 7 Mouse properties called Allow Themes to
change mouse pointers. That may effect the intous/photoshop.
Actually, this seems to have fixed the problem. No idea why it was suddenly causing a problem though, Photoshop CS5 has been working well for months. It's under Control Panel > Hardware and Sound > Mouse > Pointers > Allow themes to change mouse pointers (turn off).
