Jim,

I checked, was not enabled, so I enabled it, but this doesn't seem to
be the issue.

After that, my Mac colleague and I did some digging in the files
When I send Mac a working file, and we look into the file as a .zip
file, he sees the same folders & files I do.
When Mac opens the file in Excel and then saves, and looks into the
newly saved file as a .zip, the customUI folder is missing!

He manually copied the customUI folder back into the zip version of
the file, sent me the file, and there are a bunch of 0kb files, all
named the same as the folders, as well as a MACOSX folder & 0kb file
that he can't see on his Mac.

Any ideas? It appears that when the Excel For Mac saves the file, it
strips out my customUI, and potentially adds a few system files. when
I tried opening an earlier copy (that he had saved & sent me) as a
zip, I get an error that the zip file is corrupt or invalid.


We're going to dig a little more, but if anyone has an idea on where
to dig, it'd be appreciated!!

Jim,

so I tried your suggestion. *didn't seem to hit the Stop, which would
indicate the RibbonOnLoad is never getting called post Mac, correct?

Anyone know what would cause that and how do I fix it?
