A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I also agree...this is a pain the you know what...it did not always work this way...definitely a bug...I am going to try to model suggestion for now
I've done some more testing of different situations.
What I found is it only changes from relative to absolute under some circumstances. It may be related to enabling macro's, but doesn't seem to be a problem with the same spreadsheets when I open them with relative references in Excel 2010 and then save them to a different name.
I had a Microsoft support chat remote into my machine, and when he did that I couldn't replicate the problem by saving a spreadsheet to a different file name. However as soon as the remote login was disconnected, the problem occurred again.
Not sure how to demonstrate this to Microsoft so that they can troubleshoot it, but I'm going to use Excel 2010 until they do and check that it doesn't change references to absolute.
