How do I exit from a running packaged project?

My packaged project for Win64 works fine but I don’t know how to exit from it. The escape key doesn’t work and none of the mouse buttons do anything other than navigate through the project? So far I have to either Alt+Tab to get a window I can close or use Ctl+Alt+Del into the Task Manager. Any help would be appreciated.

ALT-F4 - or write a menu :slight_smile:
