I think this is pretty much the expected behaviour. If you want to make sure that only one instance of your programm is started - which can be pretty challengeing - this is another issue. Pls let us know which language etc. you're using.

This codeguru article might be a good starting point anyways.

In C# terms you might find this devblogpost interesting.
