 This is
 because the menu name is "Utility" and the project
 options say that
 "form controls are
 public".
 
 So what
 happens is: the compiler creates public variables in the
 form which
 have the name of the controls in
 the form (I guess), so that the programmer
 can write FMain.myMenu to access their menu
 control. But Utility is actually
 a boolean
 property of the Form class already from which FMain
 inherits, so
 the not-so-strange
 "incorrectly overridden" error is raised.
 
 Our friend did two things
 wrong here: normally, you shouldn't tick the
 "form
 controls are public"
 checkbox. Indeed the program seems to not need it at
 all. It's the same as having everything be
 a global variable -- it nullifies
 the
 principle of encapsulation.
 
 The second thing is to violate the Gambas
 naming conventions :-) Calling a
 thing
 "Utility" asks for trouble, "mnuUtility"
 would be fine.
 
 Regards,
 Tobi
