Not that I know.
A workbook uses the memory from the PC of that user.
As long as the workbook doens't contain a macro which opens another
workbook, I can't find a reason why this might be a problem.

I have a read-only workbook which could potentially be opened
simultaneously by many users.

Will the workbook and the macros in it slow down proportionately to the
number of users ? Will the macros "screw up" (I know this depends on what
the macros are doing but assuming they work fine for one or two users) ?

Thanks.
