Is smooth scrolling broken in Windows 7 x64?
It is enabled in both Internet Options and Performance/Visual effects
Windows Explorer doesn't even make a pretense at smooth scrolling (only scrolls jerkily lines-at-a-time). Neither do most other apps.
Internet Explorer is the only app that actually "smooth-scrolls".
Using Microsoft Comfort Optical Mouse 3000 with Intellipoint driver.
Do not give an answer "lower the number of lines scrolled at a time", I know about that setting, and it just slows down jerky scrolling, it's not what I'm looking for.
