Same exact situation here using 32bit windows 7 bootcamp install on my early 2009 macbook. Worked fine prior to this 5.1 safari update.

Same problem on windows 64-bit machine.
Scrolling is very laggy and slow.

Same for me on Windows 7 Professional at work- scrolling hardly works at all. I have to almost spin the wheel ala wheel of fortune to get it to move at all.
Anyone have any clue?

I tought I was alone, but it seems Apple introduced a new bug in 5.1. The scroll wheel does no longer work in Windows (7 64-bit). Could this be a side effect to the scroll behavior changes made in OSX Lion for the Macs? I just hope Apple reacts quickly, as it is a frustrating little bug. Fast scrolling to get to the meat is quite important these days and I use it a lot.

Same problem is intermittently present in iTunes, so it could be a system-wide change made for OSX Lion and we are getting the fluke. I just found that the two-finger scrolling works fine on my new Thinkpad X1, so the problem is just with the mouse wheel.

Same exact problem on my work machine running windows 7 32 bit. very frustrating and hoping for a quick update to this bug.

Have just installed the latest Safari version on Windows 7 Professional 64-bit and have the exact same issue as previously reported in that scrolling is extremely laggy.
I use 'KatMouse' on my Windows machine to enable me to scroll which ever window I mouse over without having to activate it, same as you can on a Mac (I strongly recommend trying 'KatMouse' on your PC if you haven't). Anyways, I thought KatMouse might have something to do with the lagging but that's obviously not the case given that other people are experiencing the same problem.

If it makes you feel any better, I have a 2006 iMac, and the scrolling in Safari 5.1 is terrible. It's not just windows. iTunes uses safari to render certain things, so that may be effected also.

Having the same problem on Windows 7 32bit. After the update, I've got a broken scroll on Safari 5.1. Any clues if Apple is aware of this issue? This is annoying.

I too am using Windows 7 32 bit with a Microsoft Wireless Mobile Mouse 6000. Scrolling is very slow. Eventually it will scroll but after many revolutions of the wheel. I cannot replicate the behavior in iTunes 10.4 though.

Same here, have to spin the mouse wheel like crazy to get a bit of scrolling action. Win 7 64 Bit, Microsoft Mouse, no IntelliPoint Software installed.

Same here. Have to spin the wheel real fast and it will scroll, very jerky though. Windows 7 Pro 32bit. I would hate to have to switch back to firefox...

A lot of people are reporting this. I use Win 7 Pro 64 bit at work and Safari 5.1 scrolling is broken with the mouse wheel. I use a Logitech MX mouse. So what I did to work around it (for now) is to use the tilt buttons on the mouse wheel. I assigned left to page down and right to page up. It's kludgy but it works. I hope 5.1.1 comes out soon. No problems with my Mac at home, though.

I have also had this problem and managed to find a workaround.
The issue on my work computer was related to a Microsoft mouse with smooth scrolling, it seams that the new version of Safari does not support smooth scrolling properly.
With the Intelipoint software installed go to:
Control Panel >> Mouse Properties >> Wheel
And click 'Identify programs that don't scroll correctly...'.
Click 'Add' and add Safari to the list.
Click OK to close the windows.
