What is happening:
After sending a message with the speech bubble instead of pressing enter you are unable to move, move the camera or use hotkeys other than TAB, f12 or esc.
To be able to do stuff again you need to either try to type something on the chat or simply pressing esc to bring the menu.
What should be happening:
Sending a message like that shouldn't make you unable to do the mentioned above.
Steps to reproduce the issue:
Type something, a command also works and send it with the speech bubble, then try to move or open the inventory or the journal.
