I have run across an oddity in Exel 2010 Trial Edition. If I define a range to be cells c1, d1, f1 and g1 using the Name Manager and then put the following in another cell: =Sum(range name), the function returns the proper value. BUT, each time I open the worksheet after just viewing it (not changing anything), Excel asks me if I want to save the changes. I didn't make any changes so why should it ask me that? Is there a solution to this? Thank you.
