Ok we have had this issue more and more, I have detailed the steps to reproduce, as prefer our sessions inbuilt.
1) There is an RDP session open to the remote computer in a tab
2) TeamViewer is active in said remote session to let someone else control the session
3) Mouse positioned anywhere over RDM window and another tab is open (be it RDP, SSH or any other connection type)
Mouse moves as the person at remote end of TeamViewer controls it. Clicks don't get passed through to another tab, just mouse movement.
4) mouse moves even if another program window is on top of RDM and that program is focused.
