Yes, you are right, CAD is intercepted by OS, but it is also sent thru RDP connection, so you can dismiss your system window. In my opinion better way to send remotely CtrlAltDelete is by pressing some button in menu than by using Ctrl-Alt-End but whatever nothing of my concern.
So I have tried all shortcuts that I can think of. woks: ALT+TAB ALT+F4 CTRL+W CTRL+R CTRL+T CTRL+Q CTRL+ALT+DELETE (happens on local system and also remote connection) -- Sent from: http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/
