I don't know much about dropbox, What I need to know is where does it create a idb file? on the dropbox or on the computer? One solution can be create a tempfile in the drop box. If the file exists then other application will not continue. idb file will not be a solution. And the whole process is odd and useless. This is not how you should make a multi-user application

It is recommended for the temporary file to use the "lock file" mechanism.
Create lock file, use resource, unlock.
