When I run following passages (first the code marked 1st, then the code marked 2nd, and last, the code marked 3rd), 1st: 100 RectangleMorphs draw to the screen 2nd: they change position 3rd: they disappear.
If I use BlobMorph instead of RectangleMorph, both Squeak and my computer freeze. Other than the obvious (don't do this with BlobMorph!), why is RectangleMorph ok in this circumstance whereas BlobMorph isn't.
Thanks in advance for all help ....

" 1st-----doit " theBag := Bag new. x := 10. y := 10. xIncrement := 4. yIncrement := 4. 100 timesRepeat: [
theMorph := RectangleMorph new. theBag add: theMorph.
theMorph position: x@y. theMorph openInWorld.
x := x + xIncrement. y := y + yIncrement. ].
" 2nd-----doit " theBag do: [ :eachMorph | eachMorph position: (600 atRandom)@(600 atRandom) ].
" 3rd-----doit " theBag do: [ :eachMorph | eachMorph delete].
I can't be much help except to say it does the same on mine, during the 1st doit. Hitting cmd-period gives me a debug box, but the system remains non-responsive.
Clearly this is a bug. I suggest you post it to http://bugs.squeak.org/main_page.php

What image are you using? It works on my image (Croquet) using BlobMorphs, although updating the blobmorphs takes 100% cpu, the image is still responsive

I'm running Squeak3.9-final-7067.image

If you're planning on doing a lot of morphic work, use the etoys image, which has lots of morphic bugs fixed. Squeak.org images are the most broken with regard to morphic.
Thanks.
And just to be sure, where exactly should I get the etoys image?
Thanks again -

The web page is http://wiki.laptop.org/go/Etoys Direct link: http://etoys.laptop.org/src/etoys-image-and-pr.zip
Thanks Mathew,
As soon as I asked the question, I googled etoys image and found the link and followed the instructions.
This now works on my MacBook .... although 120 seems to be about the limit, maybe a few more ...
120 timesRepeat: [
b := BlobMorph new. b position: ((500 atRandom) @ (500 atRandom)). b openInWorld. ]
And
BlobMorph allInstancesDo: [ :b | b delete ]
works too. Although it seems like the image is almost at the point of thinking about maybe starting to freeze ....
My next question: To the best of my knowledge, there's no real comparative information on the web to suggest one version over another. Can you give some guidance on this or point to a link wherever it might be?
Thanks in advance,
Mark
P.s. Scott Wallace did suggest the etoys image a week or so ago on squeak-dev. That advice is now making a lot of sense. So thanks, too, Scott :)

No, nothing I can think of. Just familiarity with what is going on in the community.
Squeak.org and squeak-dev/web are mostly focussed on using squeak as a development environment, and not an end-user application, and so have allowed morphic/etoys to decay. Squeakland and etoys are centered around morphic and so keep it in tip-top condition. The other forks (croquet, sophie, scratch) mostly use code that is unique to that other fork.
Thanks. That's all helpful to know.
.... I'm hardly in a position to critique _anything about Squeak .... but having said that, it seems like these kinds of differences should be documented or alluded to in some kind of concrete fashion. Relative to Squeak advocacy, these kinds of differences would seem to be very essential.
Well, just my opinion at the moment and certainly, THANKS AGAIN, for taking the time to explain.
