"Show Desktop" Shortcut Blowing Summoner Spells Instead

Using the 'Windows Key' + 'D' is the standard shortcut for showing the desktop. Since the patch last night, the game no longer registers the windows key being pressed and instead only senses the 'D'. For anyone (moron f is for flash) who sets their important summoner spells on 'D', this is devastating and needs a fix.

A reason for this is possibly due to the fact that the game no longer registers the windows key since pressing it in game wont bring up the Start Menu either.
