[plt-scheme] Startup Problem

This is a bug in an easter egg (argh).

You can fix it by either changing your date to anything besides july
30th, or by changing the definition of on-paint in the definition of
splash-canvas% in collects/framework/splash.ss to this:

   (define/override (on-paint) (when splash-cache-bitmap (send
(get-dc) draw-bitmap splash-cache-bitmap 0 0)))

or by getting the latest in SVN.


PS: Happy birthday, Eli!
