I changed the curser to a big one months ago, because I kept loosing it. When I Upgraded to 3 I got faults. The faults were drop down boxes were illegible, Scrolling control on my wheel mouse was Jerky and most importantly whenever I clicked an Icon it took an age to boot the program. But now I've changed it back to a resolution dependant curser the faults have gone away.
The whole distribution doesn't seem as quick:One flew, two was slower three would be unusable if I can't sort the bug.
