Comment 2 for bug 683328

Intriguingly, if I am in the middle of an alt-tab, it will accept clicks. So if I press alt-tab, then keep holding alt, I can interact with unity like normal [1] until I let go of alt. Then it stops accepting clicks again.

[1] Well, mostly normal. Indicators will look 'depressed' when clicked, but no menu appears and don't become 'undepressed' on a second click. Not sure if that's because I'm in the middle of an alt-tab or if it's also part of this bug.
