An Excel 2000 user has a fairly large workbook file (almost 2MB)with multiple worksheets within. It typically takes ten minutes or more to open. I have made as many modifications to the Calculations page in the Tools Options dialg box that could be causing slowness, but that doesn’t seem to help. The user stated that this was not as big a problem before when it was a ’97 Excel file. She has a good pc, plenty of processing power and ram. Cannot figure why it loads so slow. Once opened, it works fine and has no error messages, circular reference errors, or the like. Please help! Thanks.
