Make sure that SMIL playback still works, it uses keyboard
and mouse
events. The site will normally do this by itself but it
depends on
how the XWindow gets created. copy both of the attached
files into
the same directory and play back the .smil file. You should
see a
few 'x's. Click on the top left one and all the 'x's should
start
moving around the screen. You can try this with 'splay' to
see how
it should work.

If that still works then the change looks good.
