[Newbies] RectangleMorph vs. BlobMorph

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 ....
