Please modify the chat interface so the remote access control user cannot accidentally enter chat text in to the guest chat box

Its way too confusing when your connected to a host session and you are chatting with the guest user... which box to enter chat text... it cant be just me that almost always accidentally enters my chat into the guest chat box.  Its one thing that the guest doesn't see or ack the chat initiation but the ability to accidentally enter text into wrong box seems like a bigger issue.
