Excel XP, Windows 2000

I have a worksheet that formerly had recorded macros (not VBA) in it.

I deleted all the macros (none show up in Tools/Macro.../Macros), then saved
and closed the file.

When I come back in, I still get the warning about macros in the file.

Any ideas on how to really clean out the macros so that warning no longer
appears? (Interestingly, I had some VBA code in another file and deleted the
VBA - no warning.)

Thanks for any suggestions.
