I know this is an old post, but it's the only one I found relating to the Enter key Send issue in Chat. Have those changes been applied already? I'm experiencing a situation where, when in Chat in the Viewer app, I can send my text using Enter, but the other person on the other end, with Host running on their machine had to click the Send button to send text in Chat. Both are running the current software version, 184.108.40.206. If this has been already addressed, please point me to the right forum post, otherwise, I would like to file this asa bug.
