Autoscroll is not working properly for me since upgrading to 10.2.1. I have replicated the issue on two different Macs, both running Mountain Lion. Autoscroll is now choppy and very slow, and adjusting the speed in preferences has no visible effect on the scrolling speed for me. I use autoscroll in spurts (when I'm doing a lot of reading) so I am not sure whether this was a bug in 10.2.
Can anyone else replicate this? Is there something else I should try to fix it? Thanks in advance!
