Binds And Crashing Issues.

I have some windower binds that tend to crash me (I'll get crashdumps next time this occurs, just added crashdumps, but I have a more important question to me, just explaining the issue.) The binds in question are:

bind @i input /satchel
bind !i input /sack
bind ^@i input /wardrobe
bind !@i input /case
bind @0 input /friendlist

If I have other UI elements up (friendlist/inventory screen/equip screen/etc), these macros will often crash me, is there a character I can add to the bind to make these macros not work if such a UI element is up, like % does for the chatbox?
