Cursor in OK Code: I'm adding an inputfield to the main screen. Is there a way to prevent the cursor from going to this created inputfield automatically?  We would like the cursor to go to the command bar by default.

This is the standard behaviour in SAP GUI and we can't overrule it. As a workaround you can replace the InputField with a DropDownList. Since this is a GuiXT element that is not directly known to SAP GUI, the cursor will stay in the OK Code.
