This one fixed my problem with the erratic cursor on the mxlaser 1000 mouse that comes with the mx 5000 keyboard. all previous versions, 2.6, 3.0 fixed it somewhat. I am happy now, at least they admit the issue on the support site and suggested to update; however; you won't have this 3.01 version there yet.

I can't even see v3.00 on the Logitech website - I only get offered v2.60. I have downloaded it from the link posted here - but is v3.x not considered final enough to put it on the main Logitech page? W.

OK thanks. It doesn't come up when I select the diNovo desktop though - it still only offers v2.6 :-( W.
