Can't determine why Excel 2003 file size is growing.

Stripped my spreadsheet. Erased all VBA macros. Dumped all temp files.
Last Cell & UsedRange don't appear to be issues. Not tracking changes. No
pivot tables.

And still I wind up with 2.56MB sitting somewhere. I originally posted
recently under subj of "Excel File Shrink". I started with a 3 MB file that
with very little additonal data entry grew to 60MB.

Hopefully somebody out there has an answer before I have to pony up and pay
MS $245 for Pro Level tech support.

Thanks,
John
