Can anyone try this and see if it's just my PC or is infact some sort of bug.
Open VLC Media Player, but leave the window open in the background (I have music playing)
Now when you open the page containing the Web App, you can't click nothing because VLC always becomes the widow that's being 'used'.
Only solution is to either minimize then maximize your web browser or keep VLC closed down.
I'm using Firefox as my browser.
