Safari 4.0.3 update has problems, AVOID it

Question

I was browsing Lotus Talk (www.LotusTalk.com) specifically this thread of mine:
http://www.lotustalk.com/forums/f100/hod-infineon-7-4-09-ouch-75545/index2.html
When I used my Logitech scroll wheel I got the spinning beach ball after every scroll -- oddly you have to wait about 1 minute with the site open before the behavior happens. Once it happens it affects EVERY Safari window I have open, goes into "slow motion" typing text, scrolling, everything becomes super slow with frequent BeachBalls. Wasn't behaving like this under Safari 4.0.2.
Anyway, you folks might want avoid this update. I hope a 4.0.4 comes out soon as this problem has render Safari useless on my MacPro.

Answer 1

Barry,
So you've made an assumption my Logitech wheel is at fault -- sounds like you've made some assumptions without any evidence. Have you actually gone to the link I listed and waited a minute or two (make sure the entire page loads and that you are on page 2 of the thread)??
It's pretty simple: Safari 4.0.2 works fine with the exact same link, same hardware, Safari 4.0.3 does NOT work on the same link and exact same hardware. Seems to me that it's clearly a Safari problem. Hence my post of caution.
To replicate:
1. Goto link I listed
2. Wait for page to load and make sure you're on page 2 of thread
3. Wait 1-2 minutes
4. Use mouse clicks to scroll or scroll wheel or whatever method you like to scroll (mouse type is irrelevant).
This produces very slow scrolling and/or beachball. Once this happens open up a separate Safari window and goto this forum (Apple Discussoins and create a new post and start typing, typing is VERY VERY VERY slow.
The problem seems to only surface at the specific link I presented in my original post, other sites seem to work fine.
And again, 4.0.2 doesn't have the problem 4.0.3 does.
