Data not shown for clients

[blissland]

I have an FMP9 db that is served on FM9Server. Everything seems to operate normally, except one calculation field (shown repeatedly in a list view) that doesn't show data to some users when more than one user is logged in. Its not a user priv issue, because if only that user is logged in, the data is displayed.

Is there a known reason why a second user would not have a calc field display?

Its possible that I, as the first user, may have been in a record involved with that field, but that would have only related to one record, not every record in the list.

Does the calc happen to be global?

the field itself is not a global and no global value is ever part of the calculation. i do have some global fields in the db. i would say that the calculation is the 'longest'...as it is adding the SUM of 3 fields from related tables: sum x + sum y - sum z. I questioned whether its just a delay in processing but then why would the first user not have to wait long for it?
