application running in background after it was closed

[danieLs0xFF]

I think i have found the problem.

when handling escape key in OnEvent function i need to return true after i call closeDevice() to let the engine know that the event was processed.

thanks CuteAlien for advice i'll move the beginScene , endScene in statemanager->Run()

and thank you all for help

I did actually mean the CApplication::Run() ;-)
A statemanager should not know about rendering - it's managing states. An application on the other hand needs to render.
