Motion 5 cannot be opened ??

Does this make sense ? On my iMac I have defined multiple users and one of them has the Motion5 app opened. Now I want to use the app on my account and with any other app that is perfectly possible: multiple users have the same app open. It is so obvious, I never even gave it a second thought. But Motion 5 appears to be different, because if I try to open it, I get this message saying I cannot, because "someone else is using it". Yeah, so what ?

I have been looking around on the internet and found no hits on this issue, so I appear to be the only one having this problem so it's probably my fault, but what can I do about it ?

Aperture 3, OS X Mavericks (10.9), Time Capsule

That is how Motion and most apps work. Unless an app is coded to open multiple instances of itself, only one instance can be launched and running. Different user accounts still run on one computer, one instance of an app on one computer, that's it. The other users will have to learn to quite all apps before logging out of their account.

Just check Activity Monitor and you'll see you are incorrect multiple instances of the same program for different users DO exist and are normal. Only Motion 5 is different of all the apps `i am using

Again, the app has to be written to allow that. Motion isn't, thus, I am correct. Motion isn't because of the amount of system resources required. Two instances would grind any Mac to a dead halt.
