I recently upgraded to Microsoft office 07 and I no longer have horizontal scrolling capabilities (not vertical, that works fine). I'm using the "Cordless rechargeable Desktop Black" Model by Logitech, it's a combo;keyboard and mouse. If anyone has any thoughts on how to correct this issue it would be greatly appreciated. Thanks

Have you checked Logitech's site for updated drivers?

Yes I checked for drivers however they said I'm up to date.

Then its probably an incompatibility. Does it work with other programs besides Office? Have you contracted Logitech tech support?
