Excel 2007 charts not showing up in their own sheet

I have had Excel 2007 for some time now but haven't used it much. I opened a
2003 spreadsheet and went to a worksheet that was supposed to have a chart I
made earlier. The chart, however, is not there. I thought this might be a
compatibility issue and tried plotting some numbers in non-compatibility
mode. The chart shows up fine until I move it to it's own sheet. I have
re-installed Microsoft Office Suite as well as Suite Service Pack 1.

Is there something I can do to make this work? Anything I might have turned
off within Excel or somewhere else that would stop this from allowing charts
in their own worksheet? I can't get to any charts that are already in their
own sheet so I am not sure how to recreate all of them. Thanks.
