Hi all,
same issue here. After having upgraded to Mavericks scrolling became an issue.
It freezes/stucks apparently randomly and in every application (Chrome, safari, preview, openoffice,...).
Tapping a bit around on the trackpad and trying to scroll nervously up and down scrolling starts working again.
It seems a stupid thing, but I must say IT IS A PRETTY ANNOYING BUG, in my opinion.
Hope this get fixed soon, even because it is not the only bug/malfunction introduced with Mavericks.
I increasingly regret my choise of upgrading to Maveriks as days go on and bugs get discovered.
I know bugs are unavoidable in new products, but, for god's sake, I would have assumed Apple being testing a new OS much better than they actually seem to have done, before realising it (doesn't matter wether it is realeased for free or not). Even because they don't have to think of hardware compatibility too much, given that you can only run MacOS on apples hardware, which means you know all the possible hardware configuration you have to take care of.
