recently I've been getting a warning, "File transfer in progress, do you want to abort" when I try to close a TeamViewer session. I did not start any file transfers. Why is this? I do use a lot of copy/paste between the two computers though, can that be seen as a file-transfer? But that doesn't explain why it say a file transfer is in progress when I try to close the session.
From general observation this happens every time there are more than one remote sessions and one disconnects. Also started happening about the same time as the "Unmute your microphone" prompt started.
