             Summary: ALT key not working with Windows Server 2012 R2 Standard
                 Key: GUACAMOLE-449
                 URL: https://issues.apache.org/jira/browse/GUACAMOLE-449
             Project: Guacamole
          Issue Type: Bug
    Affects Versions: 0.9.13-incubating
            Reporter: Charles Rolls
            Priority: Blocker


Using VNC protocol (pvnc, tightvnc) on device running Win2012 R2 with a reverse connect back to GuacD running in docker container on CentOS and client in IE 11 or Chrome 62.0.3202.94 running on Win7, when I hit the ALT key nothing happens on the device.

I am using web sockets in the browser to connect to a Java Guacamole servlet utilizing the Guacamole library in a Spring Boot app (Wildfly) to connect to GuacD. I have run this servlet on Windows and CentOs docker container with the same issue.

Thru the browser client, I'm in Notepad on the device and I hit the keyboard L/R ALT key to bring focus to the menu. I see the guacamole protocol "keys" instruction get sent over the web socket but nothing happens on the device. I originally found this problem by adding a button to my HTML page to call Guacamole JS client sendKeyEvent method to send the key combinations (L_ALT pressed, TAB pressed, TAB unpressed, L_ALT unpressed). I have a button for Windows key and CTL+ALT+DEL also. The Windows key works and the funny thing is the CTL+ALT+DEL works sometimes but ALT+TAB never works.

Everything works fine with device running Win7 or Win10. It is only a problem with WinSrv2012. I tried all combinations of the sendKeyEvent method with things like delay between key press / unpress. That is what lead me to just seeing what the keyboard ALT would do instead of clicking a button to do the sendKeyEvents.
