Yes. I usually alt-tab out of the client on my Windows box and use some other apps for a while. Or step away from the PC for a bit. I go back to resume my session, and my mouse and keyboard no longer work on the remote Mac. I can see the screen, but not do anything. I can move the mouse around, but it won’t click on anything. Same with keyboard, does nothing. I have to close the client and reconnect to get back to work.
