Skype seems to have recently lost the ability to have a text chat window open during a voice call. It doesn't do notifications on the icon in the task bar anymore, either. Sigh.
I'm on the latest version and I seem to still be able to chat on a voice/video call at the same time? Are you talking about chatting with people you're not on a call with?
I'm text chatting with someone. Then I initiate a Skype call with them. The text window disappears, the window goes blue, and there's no way to text and talk.
I clicked on everything on the screen, no text window. There is a balloon icon with lines in it, I thought "aha, the text chat window!" Sure enough, it opens the text chat window, and hangs up the call.
Arrgghhhh.
Microsoft has installed numerous Skype updates. I can't find any usability improvements. Things are just shuffled around, and/or broken.
I've been using Skype for 10+ years, and am about ready to abandon it for Slack.
