When I try to scroll to the right, either using the arrow or dragging the horizontal scroll bar, the window moves briefly to the right for a second or two and then jumps back to the left. This problem happens with Office Word, Excel, Internet Explorer, and Mozilla Firefox.
Folder windows on the other hand are behaving normally (ie the horizontal scroll stays where you put it). The vertical scroll bars works normally on all applications.
When did the problem start:
Yesterday, immediately after I upgraded from Office 2003 to office 2010.
Windows XP professional version 2002 Service Pack 3
Intel Core Duo CPU E8400 @ 3.00GHz
2.99Gh,3.00Gb of RAM
