OSX “Microsoft Remote Desktop (MSRD)” redefine shortcut not works Typically on OSX remaping of keyboard shortcuts works well.

In "Microsoft Remote Desktop (MSRD)" it works well too but previous keystrokes still exist:

OSX &gt; System Preferences &gt; Keyboard &gt; App Shortcuts &gt; Add
Application: "Microsoft Remote Desktop"
Menu Title: "Close Connection"
Keyboard Shortcut: "Alt+Shift+W"


I can close with Alt+Shift+W and also with the default Cmd+W. 

This is not OSX default behaviour so I think it is BUG.



Does anybody have a solution?
I think it's a bug too. 

As it has 2 versions of Close, both Close Connection &amp; just Close [when there's no window open] I thought adding both those as key commands would do it - but no,  Cmd ⌘   W   still closes the connection.
