 		Use this switch to allow Solid Apple (AltGr) to be used in combination with regular keys.<br>
 		When AltGr is pressed, Windows only sends a WM_CHAR message for (eg) international key codes; and so by default the emulator doesn't explicitly send a WM_CHAR message for regular keys when AltGr is being pressed.<br>
 		NB. Using this switch may prevent international keyboards from being able to type certain keys.<br><br>
