A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Did you get any joy from Microsoft on this? I have the same issue. I am a "standard user" of excel 2011 and it's great apart from this one issue. My sheet has 350 rows and any filtering makes navigating the sheet impossible. Scroll happens several seconds after moving the mouse wheel. When filtering is off it is quick and snappy.
To give you an idea of how slow it is I will boot up Windows in Parallels and use Office 2010 as it works as it should speed wise rather than use Excel for MAC. I think this is a bit of a shame - it's certainly a pain.
Elsewhere on the web I have seen references to removing duplicate fonts as a remedy but that didn't work for me.
Any Ideas?
