My PC, which runs on Windows 7, has MS Office Starter 2010 installed. Up until a couple of weeks ago, when you opened a spreadsheet in MS Excel Starter it came up almost straightaway. Then, for some reason, it suddenly started taking up to half a minute to show the spreadsheet. Similarly, when you close the individual spreadsheet down, it takes a long time to disappear from the screen. Anyone got any ideas as to why this might be happening? Thanks.
