Caused by a bug in the recent Q824145 patch.
Microsoft probably knows about it by now.
By the time we get used to this 'new'
feature Microsoft will fix it!!
------------------------------
Maybe this is the way scrollbar is 'supposed' to work:
Position cursor 'close' to the top/bottom of the
slider and it will scroll one window. Farther away
from slider and it will scroll farther.
Use the mouse wheel to scroll.
See mouse properties to adjust wheel.
Press/Hold/Slide actual bar.
Use keyboard shortcut keys:
Up/Down Arrows (See mouse properties to adjust)
Pageup/Pagedown (This is what you want?)
Home/End (Top/Bottom)
Right-click scrollbar...
Menu pops up...
Select option ("Scroll here" is neat!)
========this MIGHT help=============
"Try" turn off smooth scroll...
