Esc key tainted by addons...

[wellbeing]

I've noticed that some of the addons I use disable my ability to use the ESC key to perform normal blizzard actions. (ie: clear target, bring up game menu)

Now my own addon is doing it and I'd like to know why. A search on the forum for 'esc key', 'escape key' and 'esc' brought up a total of 3 posts, none of which address this issue.

Anyone know wtf this is all about?
