I have seen a few people posting around the web about this problem, but seems like its not too many. The scrolling is horrid in my Safari, and video stutters and often major beach ball action. Seems like its mostly Flash video (is this a fight in my computer between Apple and Adobe)?
Yes, I have a few pages with several tabs open, but it will do so even with just one or two pages, so its not that. I also have various extensions installed in Safari, but this was happening prior to that so that can't be it either. I had this happen earlier this year with previous Safari, but an update cleared it up. Firefox operates perfectly. So, why don't I just use Firefox? I like Safari better, but I don't know for how much long. 
Any ideas? Current
system is:
PB 2.53 Intel 2 Duo, 4 GB ram
OSX 10.6.4
Safari 5.0.2
Flash 10.1
