Steps to reproduce:
1) Open the project attached by user.
2) In /Assets/_Scenes open scene '02 Football.unity'
3) Make sure 'Maximize on Play' is deselected (otherwise the Inspector won't be visible)
4) Enter play mode
5) Start clicking on any items in the Inspector
> The whole system hangs/becomes unresponsive, a reboot with the power button is required.

*Note: all other programs in the background seem to be working after the system hangs (for example - music player is still playing, etc.)
