Esc Key Blues

I use the ESC Key to un-target things when the need arises. Recently, however, I noticed that it doesn't just untarget something but it brings up the options menu at the same time. It seems something changed to cause this to happen, but I haven't the slightest clue what it could be. I've checked my options and addon options but cannot seem to find anything that fixes this issue. If i remove ESC from the key binding then it doesn't do anything at all, not even removing my selected target. It used to only bring up this menu when i had no targets selected, now I have to push it twice cause it puts the settings menu in my way. Is there a way to change this back? I know its OCD of me but still it didn't always do this and if there is a way to switch it back that'd be awesome.

it is the same for everyone.

a temporary fix is /reload (but you need to do it everytime you log-in)

Edit:
There is even this workaround: http://forum.warmane.com/showthread....=1#post3047440
