Cannot open excel file when another is already open
 

I can open an existing excel file with not problem. However, if I try to
open another excel file while that first is still open, the first excel file
ends up "pasting" some type of iink to the file I tried to open. Not a true
link, but it pasts the path (C:\mydocuments...etc.). In other words, I
cannot open more than one excel document at a time.

Any help?
