Cursor movement not smooth in Photoshop

Hey,

I just decided to try out Vista and installed the 32bit version. Following that I installed Photoshop CS3, but when using it some weird problem occurs.

When I use certain cursor types (for example the marquee tool or brush) the movement of the mouse feels a bit "laggy" or wobbly - it's difficult to describe. It's not as precise tracking as if I use move tool or the color picking tool (eyedropper tool it's called) - when I use these tools there are no problems at all and the cursor movement feels good.

This issue seems really odd to me - does anyone got some possible explanation to this?

For your information my hardware setup is like this:

Intel Q9450 2,66 Ghz cpu
4GB DDR2 memory
Asus P5K/EPU motherboard
Club3D 8800GTS 512MB graphics card
Razer Deathadder mouse

I hope someone can help me out Tell me if you need more info. Thanks in advance.

Sometimes the cursor movement can be described as gritty, it really just doesn't run smooth - though it's still not the case for all cursor types as describe above...
