Karmic installed, mouse problems

[john]

Thanks for the tips! I managed to install Karmic by de-selecting all UBS
packages, including audio. 

I'm shocked that I still have problems with this new version too!
Without anything enabled (nvidia proprietary drivers, any software
installed) I get a sluggish mouse! (its a logitech laser, wireless)  

I checked to see if the whole system was sluggish but processes are not
eating up CPU and keyboard is responsive. 
Anyone know why the mouse is acting weird? I've had it before in UBS but
never on the generic kernel. I've googled the problem but no real
solutions found.

Many thanks!

John
