Ok, so i recently installed ubuntu 8.10. I've used a couple earlier ubuntu version, but as far as user level goes im pretty much as beginner as it gets. My problem is that whenever i burn a dvd, copy files to the hd or install something, everything else almost slows down to a halt. the mouse pointer stutters, it takes forever to switch between programs on the desktop.. just seems like it can't handle more than one task at a time. Any ideas as to what causes this and how to fix it? It hasn't been like this on earlier releases.
EDIT: Actually it doesn't happen when installing something. my bad.
