To close a independend application (a Chat program)
I need to know if my application is the last instance of this application running on a system.
I can of course iterate through all proccesses, but I was hoping there would be a simpler way to achive this task.

Using Counters to keep track of the number of instances is not a way 'I want to go, for it would flaw on a crash of any instance.

A mutex would be a problem if the first instance is closed first...

Does anyone know a simple straightforward solution to this problem?

Thanks in advance,
