Unstable Connections

Hi Guys,

I have been using RealVNC for many, many years. This latest VNC Connect seems to be a bag of bolts by comparison. I have frequently had an issue recently where the connection loses it's mouse control, the screen keeps updating but the mouse control stops, so does the keyboard. I noted today that it seemed to be triggered by switching from "One Screen" mode into "Split Screen mode". I noted that the mouse worked when on one screen, but not the other. So I switched back to One Screen mode, as soon as I used the mouse on the other screen the connection failed and the application crashed.

When it crashes like this is leaves a zombie connection, and I can't log back into my remote machine. I did until last week have a second concurrent login, purely to enable me to reconnect when this happens. However when they wanted £200 for the privilege on renewal I dropped it.

- Any suggestions on what may be causing the mouse issue?

- Any suggestion on how I can reset the zombie connection? 

I've been using RealVNC for at least 15 years... never had so many issues.
