I use the std wow chats and after the patch both the general and combat have ? for a title.
The funny thing now is general was on the left and combat was on the right of my screen.
Now the screens are in the same place but combat, right side window or should I say ? #2 window has the enter text box under it.
WTF is going on? OH OF COURSE its an enhancement.
It's probably an elemental, or resto (teehee). But, back on topic, you can drag your windows on top of each other to merge them into a single box with multiple tabs.
