| Determines if checkable menu items are
        automatically checked/unchecked when clicked or this is left to the script handler
        function. Syntax:
          VarioMenuItem.AutoCheck = boolean Parameters:
          boolean - The default value is true. That means
          VarioMenu will change the state of the clicked item before it calls the click function. If
          the value is false - no action is taken and the handler function must use
          the Checked property to select the clicked
          item. 
           Remarks:AutoCheck property is valid only for menu items which has their Type set to mitCheckable or for
        radio group members. Setting AutoCheck to false can be useful if the checked state of an
        item depends on some external conditions which are evaluated by the click function and it
        makes the decision whether to check or uncheck the item. Also disabling autochecking is
        needed if the clicked item is member of a radio group and needs to know which item from
        the group was previously checked - the click function can use the Group property to get all members of the radio
        group and see which has Checked property set
        to true. Applies to:
