I have a file that is linked to a very large budget file (25 megs) that is
supposed to pull info from the various sheets. When I "change source" after
having renamed the budget file, it simply hangs up with the hour glass
.....any suggestions?

I tried a find and replace (with the file name version), but it didn't work
on a global scale -- it hung up too. It worked on an individual cell basis
however.
