If you're using anything less than Excel 2007 and you've used columns A:IV
(256 columns) then I'm afraid you're out of luck - that's the absolute
maximum allowed.

If you've not used all those columns, then there must be some hidden columns
(which is why it's blank to the right of your used columns).
