graph won't update when data is changed
 

I've tried everything imaginable and can't get charts to update when I edit
data. This was never a problem in Office 2003. The problem seems to be
related to how Excel 2007 saves files, since when I first create the charts
everything is fine until I save the file (in xltm format) and then reopen it.
I just doesn't seem like Office 2007 is ready for prime time - on did I miss
the memo: Is this version still in Alpha?
