I have a workbook with macros that I need to distribute to users. I'd
like to expose macros through toolbar. At first I thought, I'd just
attach toolbar to workbook, but then I thought of this situation:

book named "test1.xls"
give to user
user saves to d:\temp\test1.xls
user opens and gets toolbar
user decides to move test1.xls to C:\Documents and Settings\joeblow\My
Documents\test1.xls
now buttons on toolbar refer to file that no longer exists

What's the best way to avoid this?
