Appliance Mode - Keyboard Shortcut

Hello All,

I am using WDM to push out WCM Appliance Mode to our Thin clients, but have noticed users who have the config are no longer able to use some Keyboard shortcut key such as CTRL+B, CTRL+F, CTRL+U (there could be others) but some shortcuts work such as CTRL+A, CTRL+X, CTRL+C, CTRL+V work.

If any has ideas or insight into this it would be very appreciated.
