How does Excel Sheet with combo box show it when used projector?
 

Excel sheet have couple of combo box and command buttons. When projected with
In-Focus OH projector or any other projector, it shows only red X mark for
these object on laptop screen as well as on the projector screen. How to make
this work?
I have tried multiple projector brands. These pull-down and combo box are
created with Excel Control and Form menu options.
