Using XP and a Logitech mouseman+ . Since updating to IE7 when using the scroll wheel my scrolling overruns in approx 1 sec steps for 4 lines in Explorer, which is quite frustrating. It is fine in all other applications.
This is a known problem with Logitech mice. I had the same thing but it was solved by changing the settings. Start. Control Panel. Mouse. Choose the Buttons tab. For "Scroller", set to the following: Check the box labeled "Use MS Office compatible scroll only." Also, check the box labeled "Scroll in active window only." Hope this helps.
