Death Screen non responsive

The death screen is unresponsive when full screen is activated when dying.

I've reproduced this several times all without fail.

When dying (Void, Mob, Player) and you press your computers key to bring minecraft to full screen (F11 for me), the death screen is unresponsive. You cannot press either of the buttons to respawn or exit the server/map. I have reproduced this bug on survival/creative/adventure single player and multiplayer.

Here is a screen capture of the bug: http://puu.sh/8heoa.png

If this can be fixed, that would be great. I know it isn't a bug most people would do in multiplayer, but it can effect games on servers.

Thanks,
Trials

Edit Im sorry, but my mouse isn't shown in the picture. I thought it had.
