Property Tab Builder

Every time I want to use "Property Tab Builder" I get the ?(something to the effect of) "Do you want to save changes to theExcel sheet". I always say no.

This comes up when I first select a Tab Builder in a new file,thats ok. But then every time I reopen that file it ask me again.When you have referenced more than one link to an Excel file itbecome a little frastrating. Does "Property Tab Builder " makechanges to the Exel file you set in it, if not why its asking?
