Hello I have stumbled upon a bug within the user interface.
While within the chat dialog there is a bug when one hits the HOME KEY on the keyboard. It will jump out of the chatbox and create a second userinput (this is the default chat dialog of the UE3).
I observed it in the ending lobby after a completed match (in this case the chat-windows is in the top right corner). But it might be feasible for the chat menu in general, did not test that yet.
To reproduce:
wait for the match to end
while in the closing lobby, open up global chat via hotkey
then hit the HOME key on the keyboard
Result:
the default UE3 chat input will appear in the lower screen
