A XbpRadioButton used with a manifest file is displayed with a wrong
caption. It is black foreground on black background. Only the radio
button itself is visible.

This problem appears only when the radiobutton is a child of a
XbpGroupbox instance.

XbpPushbutton objects will be displayed with a black border around
the object in the same case.

A fix for this problem is available via Public Fix Level (PFL)
182306. Please visit www.alaska-software.com (support section)

Try setting the :clipChildren instance variable of the group box's
parent to .T. (TRUE) before calling :create(). In most cases, this
will be a dialog's drawing area. However, if the group box and its
childs is placed on another XbasePART, eg. a tab page, that object's
:clipChildren setting must be changed. Example:

  // Create application dialog, contains a group box
  // with radio buttons. Note the change of the
  // :clipChildren setting of the drawing area
  // that serves as the parent for the group box
  oDlg := XbpDialog():new( ... )
  oDlg:drawingArea:clipChildren := .T.   // (work-around)
  (...)
  oDlg:create( ... )

  // Create static of type "group box" as the parent
  // for the radio button object
  oBox := XbpStatic():new( oDlg:drawingArea, ... )
  oBox:type := XBPSTATIC_TYPE_GROUPBOX
  (...)
  oBox:create( ... )

  // Create radio button object
  oRd := XbpRadioButton():new( oBox, ... )
  (...)
  oRd:create( ... )
