It
is a feature in 2007.
I've attached a screenshot of what I mean. The screenshot was taken while I was using Excel 2007.
When you right click on the cell, you have to make sure that it is a cell within the query table - not just any old cell on the worksheet - otherwise you won't see the "data range properties" option in the menu. The example I used for the screenshot uses a query table to import a text file - this was just for convenience - I know you're not importing a text file, but the same property applies to your situation too.
If you don't have this option then you're not using a query table. If that's the case then you'll need to give us more information about how you are importing the data. I do know a workaround which can be applied to your formulas to prevent it happening, but it's really ugly so I'm hesitant to suggest it - it'd be much better to fix the import itself.
