Horizontal scrolling not working in Office 2003

[Guest]

Using an MS Wireless Intellimouse Explorer 2.0 and the latest Vista 6.1
driver, horizontal scrolling would not work in Office 2003 after intial Vista
setup.

Mysteriously, a week later it suddenly worked, and very nicely at that. It
may have been related to a run of Registry Mechanic shortly before, but don't
really know.

After 7 MS Office automatic updates on the 15th of this month, horizontal
scrolling no longer works in Office. It does work in a few places elsewhere -
- like in the mouse driver settings dialog boxes.

Any help? My reflexes are really getting confused!

For what it's worth, I found a simple cure that may or may not last: I just
unplugged the USB mouse and plugged it back in again. Don't know if this will
survive restarts etc, however.
