Problem setting page breaks in Excel 2007

[Gouki]

Got an odd one for ya guys...talked with a user earlier today who was trying to set the page breaks for a spreadsheet. I was in a netmeeting with him and could see/control his machine. We go to page break preview and drag the page break line over to where we would like it set. Now...instead of it setting the page break there...it creates a page break around EACH and EVERY cell. So that if you go to print preview, you're looking at ONE cell and you'd be printing...oh...a couple THOUSAND pages. lol.

Anyone ever seen this before? User states that it never happened in 03 and just started since he's been upgraded. I had him forward me the spreadsheet and naturally I was not able to duplicate the problem. I set the page breaks and emailed it back to him so he was at least able to get it printed off...but after tinkering with the file a little more, the problem came right back.

Been looking through google for a few minutes now but haven't really found anything yet that jumps out at me...so thought I'd post it here as well. Tomorrow morning will most likely do a repair on the Office install and see if that helps any...

Ideas? TIA!
