Msg when an application is opening more then once

[Edu07]

Hi,

I created an access application for several users. At times, they forget
that have the application already open and execute a new one reducing their
available memory. I'd like them to be notified when they try to open a new
application. Can it be done, and if so, how?

TIA

Thank you.
Do you know if works with acc07/vista? In my case wouldn't execute.
