  VBlinkBoxOrButton creates a box (button), highlights the box (button)
using the XOR function, sleeps for some time and then unhighlights the
box (button). This button is different from the button created in the 
panel (VDisplayPanel) or the ones created by VAddButton. The difference 
is these buttons are more simpler and do not have a call back procedure
associated with them.

       from the window ID.
