I have a new desktop computer running XP Pro, 2.4 ghz processor, and 1GB RAM.
I can open a new Excel 2007 document and attempt to select cells by holding
the shift and page down keys. It will pause for less than a second and then
stop selecting even though I still have the shift and page down keys pressed.
I've disabled all add-ins and run the office diagnostics. I've also
uninstalled office 2007 and reinstalled it with no luck. Office 2007 SP1 is
installed.
