So I spend most of my day posting on forums. I'm on a Macbook, c2d 2ghz with 4gb of RAM. When I'm typing posts here, every couple of minutes the cursor in the box will freeze and stutter, then it will catch up with me after a few seconds. I'm using a Logitech Wave keyboard. I've uninstalled and reinstalled the Logitech software. Not sure what else it could be. Any ideas?
