I’m running Safari 4.04 on a Core 2 Duo Mac with 2 GB of RAM. Lately, if I leave windows and tabs open for a few days Safari gets super laggy (beach ball) and the HDD starts spinning. Eventually, it will catch up so that I can perform subsequent actions, but it’s really annoying to have to deal with. If I close all windows and tabs and restart Safari it’ll go back to normal, but I shouldn’t have to do that every time. Any ideas?
