I noticed that often if i lock my computer (host) and it had a remote session open, When i return and unlock the pc, the remote session looses access to the keyboard. Only the mouse still works. I need to disconnect and reconnect to get back the keyboard access. Very annoying...
, sounds like some control key is being stuck (Alt, Ctrl, Win-key or something else). We have fixed this in the upcoming update, please make sure to update as soon as it's available (there's a button for update in the menu) and let us know if the issue persists.
