Right this problem is REALLY annoying me now, in spreadsheets bigger than say, an A4 page scrolling is painfully slow (on both my machines). If I load VMWare with Windows 7 x64 and run Excel 2010 in there it scrolls FAR quicker. What is going on? Is it **** programming or is there a setting someone that will speed it up? Patches are up to date, system is otherwise idle, reinstalled, etc all the same. Cheers!
