show and hide virtual keyboard on MC18 with EB 1.8


What is the simplest way to show or hide the virtual keyboard on a MC18 with MS Windows Embedded 7.0 and Enterprise Browser 1.8 ?

EB.System.keyboardState is always set to 'hidden'. Set keyboardState to EB.System.KEYBOARD_SHOWN is not working !

System - Zebra Technologies TechDocs

Any help on that topic ?

Thanks & best regards
