In Excel 2007, I've opened a file I created in Excel 2003.

It looked fine in Excel 2003. But now, in Excel 2007, one cell now appears
as #############, onscreen and in Print Preview and when printed. The cell
contents look fine in the the entry line at the top of the screen, or when I
put the cursor in the cell and hit F2 (edit). The cell contains multiple
lines of text. I've tried it both with Wordwrap and without, but the cell
still appears as ################.

Any suggestions on how to get hese cells to display normally again?

Thanks.
