Weird mouse movement mx510 help?

[UnlimitedMP]

I have a mx510 and the motion of the mouse changes depending on what window I have selected.

For example, in this IE window, the mouse cursor moves fine at the desired speed. However, if I go to desktop, it's sluggish.

I adjusted the motion settings under Control Panel >> mouse

dunno what else to do.

Have a fiddle with the Logitech software that came with it, it may have certain profiles for certain programs. At least try the software, its usually better than the Control Panel setting if the Logitech stuff is installed.

Logitech program takes me to the same spot as the control panel mouse (it displays the mx510).

Use acceleration and os implantation.
I had these problems with my mx518 too.
Weird, on fastest I still find the curcor too slow, even without acceleration and on 1600dpi. Anyways, sometimes it seems the mouse forgets on which resolution I am and it gets super boosted on 1600dpi, then it lags and returns to normal.
