To those of you who have found the examples in the Intuition manual
to be sloppy, I apologize.  I tried, you know?

Same goes for Intuition in general.  Hey, I gave it a good shot.  I think
it's pretty good all in all.  But you know, I didn't finish it.  Just as 
we were coming up to the V1.1 release I split instead with my lovely 
bride on a serious, serious honeymoon.  First things first, you know?
Some of you know.

Jim Mackraz has done Intuition since then.  Jim is one of the people who 
proofed the Intuition manual (lightly) before it went to Addison Wesley.
Under Jim's tutelage, Intuition is coming up extremely well.  The things
that most of you have found bothersome about Intuition (and the
system in general) are modified and enhanced in V 1.2.  Those of you
who are Beta testers should *really* exercise that code and report any
bugs you find.  1.2 must make it out.

In V 1.1 and earlier Intuitions, even Intuition was unclear about who was
in charge of borders.  The borders often were redrawn unnecessarily.  This
could screw up your own imagery.  Also, the only facility to redraw
a portion of the window without disturbing the border was to use
the dreaded GIMMEZEROZERO window, which scared many people away, as well
it should.

These problems are well fixed in V 1.2.  Intuition does many clever things
now to avoid redrawing things unnecessarily.  Intuition and Graphics
synchronize their operations much more intimately.  The Exec is better.
The DOS is really better.  And more.  So far, so great.

Also, there are new Graphics routines which allow you to do your own
clipping of a window, so the GIMMEZEROZERO window becomes obselete
for the most part, which is just as well because the name was  
just too cumbersome, doncha know.  At Amiga, they had a sign on the 
pegboard:  a red circle around a red diagonal slash that went through 
the word GIMMEZEROZERO.  I hope it's all that it should be.  I haven't 
tried the stuff yet myself.  

I used a modified version of Neil's region management routines 
(Workbench code) for data in the Sidecar windows.

Requesters are much improved in V 1.2.  If you are using 1.1, you must
contend with their limitations.  It's not too hard.

Sorry, but requesters block in 1.1.  You can create a borderless window 
instead and get any kind of input you like.  Lots of people do this under 
V 1.1.  

If you don't mind the fact that requesters block, requesters aren't too bad
under 1.1.  Lots of people use requesters.

Under V 1.2, requesters are much more efficient and much less expensive 
to use.

Sure.  You know where you want the text to go, so go write it to your
window using the Text() routine or whatever equivalent you use.
But first, Forbid() and then write your text string into the title buffer
that you specified with your OpenWindow() or your most recent 
SetWindowTitle() call.  That way, if Intuition later does one of its many
window border refreshes, the title of your choice will get drawn.
Finally, Permit() and you're ready to call Text() just in case Intuition
doesn't do a border redraw soon enough for you.

Hope this answers your questions.   RJ
