 When Sugar is used in VirtualBox, the frame is difficult to activate using
 the mouse.  As the mouse exits the emulation window toward the top left,
 the emulator stops delivering mouse events to the virtual machine before
 reaching coordinate (0,0).

 Workarounds are either;
  * use the F6 shortcut key,
  * move the mouse very very slowly one pixel at a time until it reaches
 (0,0), or
  * turn off mouse integration mode (''host+i'').

 A solution might be to enlarge the area of activation for the frame, from
 one pixel to 4, 9, 16, or 25 pixels.  A further improvement may be to
 provide this as a slider in the frame control panel in ''My Settings''.

 References:
  * git repository https://github.com/sugarlabs/sugar.git
  * source file ''src/jarabe/frame/eventarea.py''
  * method ''!__init!__'' of class ''EventArea'',
  * each call to ''_create_invisible'' uses a width or height of 1.
