Starting Acess adp by different users

[Roland]

Hi,
if an Access project (adp) is started more times simultanously or by
different users,
Access shows at the second starting the message box
'Access is starting in readonly mode' or so.

I couldn't find any startup parameter or option to suppress this message
box. If you start the adp-file direct in readonly mode the message box
also appears.
Unfortunately we use a file server on which the adp-file is stored.
So we cannot use different adp-files for each user.
If there is no solution for solving this problem
this seems to me a big disadvantage for using adp in a
multiuser-environment.

Does anyone has an idea to solve this problem.
Thanks for help,
Roland
