Interesting.
For perspective, with respect to RemoteApp, the presence/absence of any
particular application (including the start menu) is entirely on the Windows
server. The server side of Guacamole sends the appropriate RDP mouse/key events
in response to receiving those mouse/key events from the client side, and in
return Windows sends a stream of graphical updates over RDP.
If you are seeing a start menu appear at any point, and this is not intentional
behavior on Windows' behalf, this sounds like a possible bug in Windows'
implementation of RemoteApp, perhaps due to Windows assuming that it will never
receive mouse events for regions outside the visible area of an application
window within the RemoteApp session.
As described above, we are essentially at the mercy of Windows with respect to
what appears on the screen, but if this is indeed due to something like the
assumption noted, maybe there is a way we can work around that.

> Key: GUACAMOLE-1464
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-1464
> Project: Guacamole
> Issue Type: Bug
> Components: RDP
> Affects Versions: 1.3.0
> Environment: Windows
> Reporter: Matt Miller
> Priority: Major
>
> We use a RemoteApp connection via RDP to access a program on a Windows server.
> Our program does not fill the whole client view.
> In the Guacamole client you can perform a left-mouse-button doubleclick on
> the black client screen outside of our program and then the Windows start
> menu appears. This is also possible by pressing the Windows key.
> While the Windows start menu is open you can no longer interact with our
> program.
> Closing the start menu is only possible by pressing the escape key.
> This leads to usability issues and accessing the Windows start menu or
> generally anything except the RemoteApp program shouldn't be possible anyway.
