just installed a fresh version of windows 7 64bit
and while using chrome, the scroll does some annoying jumping after the scrolling stops. (after stopping it will shift one line up and down couple times)
i've installed windows dozens of times and never seen this issue. I am using logitech revolutions mouse with set point driver suite, and can't find any settings there or in windows mouse that would address this.
it is not happening in Firefox which may indicate this is a chrome problem, but not seeing any scrolling options in chrome settings..
