SmartFTP disables keyboard volume controls

A small bug but annoying nonetheless. When my keyboard volume controls (up/down/mute) are used while SmartFTP is the window in focus, they don't work. When any other window is in focus, the keyboard controls work again.

Can this be fixed?

Hello ..

Thank you for your reply. Unfortunately we cannot reproduce the problem here as we don't have a "Logitech Access" keyboard.
However we could not find any problems with other special keys.
