Dear Tom:

	I hate to disappoint you, but Screen gadgets do NOT WORK, period,
and support for them has basically been removed in 1.2 (correct me if I'm
wrong Jim M).

	Yes, you'll have to stick them on the backdrop window instead.

Moral: ignore the Intuition manual's mentions of attaching gadgets to screens.

Question though: doesn't it peeve you that Intuition needs a rastport for
the screen (32K for interlace 1 bit plane - CHOMP) and then another 32K and
change for the backdrop window!  Seems like a waste.  I probably don't
understand all the implications, but I think if the screen were treated like
a Layer on a view, backdrop windows would be unecessary, because SMART_REFRESH
would handle all the overlapping of things.

	Paul Higginbottom.
