[plt-scheme] mouse.ss of frtime bug

Hi all,

Playing with mouse.ss of frtime demo dir fails in error... :(
"attempting to lift #<primitive:undefined?> over a signal:compound in
(#(struct:solid-ellipse #<struct:posn> 20 20 blue))!"
Yesterday couldn't play with continuations, today I can't play with
mouse.ss. Why don't you let me play? ;)
heh

BTW, is it supposed in fr-test0.ss of cdrswift to have a complete
cluttered and unreadable screen in the end of the slideshow? It seems
that one forwards the slides but there previous ones are not cleaned
up... This also happens with animations : when the green, blue and red
sentences appear they just show up on top of those shown previously
without cleaning up the previous ones. Is this supposed to be like
this?

Thanks,
