[] Many thanks to Walter Smith for hacking out Sleep. But there seems to be a problem in that the DRVR does not seem to get released from the heap when the mouse is clicked. A quick check of the heap whild in an application shows a non-purgable non-relocatable block a litle over a couple K bytes remains after sleep wakes up. If someone has a clue, this could solve some of the problems others were having running sleep with calendar, etc. BTW, I have modified the source just a little to make the apple smoothly bounce around within the bounds of the screen, like a bouncing ball.. this actually makes the code a little smaller since Random() doesn't need to be called.. but this is a matter of personal preference. Thanks again Walt, good job! Lonnie Abelbeck aluxe!lra

I think there was some discussion in the past about using multiple SUMacC
things simultaneously (e.g. using a SUMacC accessory within a SUMacC
application or using two SUMacC accessories at once) on info-mac. There was
some problem with doing this, but I can't remember what. I am planning to
rewrite Sleep in 68000 assembler sometime soon to get around the problems,
but I can't guarantee a date -- it's Christmas vacation (yay!).
The reason that space is taken up after Sleep wakes up is probably the
lack of a CloseDeskAcc. Sleep "closes" itself, of course, and I wasn't
sure whether it was safe for a desk accessory to dispose of itself. All
sorts of horrible possibilities come to mind. I'll experiment a bit with the
new version and try to find a solution.
Thanks for all the compliments!

Any opinions contained in the above could very well be so different from
those of CMU itself that it would be ludicrous to compare the two.
