Window replain problem related to the palette:

When click on the modal dialog's "Cancel!" button, the first Frame
will be repainted on 256 color mode, but not on 65536 color mode.

test case:
===========
/*
- Run the test case, which displays a Frame.
- Close all other windows.
- Click on the "Dialog!" button of the displayed Frame.
   A modal Dialog should appear.
   The Dialog should not be overlapping with the original Frame.
- Click on the modal Dialog's "Cancel!" button.
   The Dialog will disappear, and:
   ... if the bug exists, all of contents of the first Frame will
      be repainted, including the colored component, which
      displays strips of colors when it is repainted.
   ... if the bug has been fixed, the first Frame is not repainted.
