I'm still using 18.104.22.1682 on my Mac while a friend has upgraded to 22.214.171.1241.
The newer version on her computer has pop-up bubbles for every chat message when the chat window is minimized. Neither of us are able to find where to disable this feature. The difficulty arises when we minimize a chat window, but the bubbles continue to show everything the other person is typing, even when one of our kids is with us for a moment looking at something else on the screen.
We have checked all throughout the
Preferences settings, most notably the privacy and chat areas, to no avail. Ultimately, we would like to disable these chat pop-up bubbles so that when a chat window is minimized, that conversation and all incoming messages will remain private until we restore that chat box to be viewable on the screen again.
