Is there any way to spead up a spreadsheet? The speadsheet I am using is
13.2MB. If this sheet is the only one open it updates quickly (15 seconds)
if I have more than one spreadsheet open it takes 10 minutes. The computer
has a 1 gig or ram. If there is anyone who can venture to help me I would
greatly appreciate it. Thank you in advance.
