[Etoys] morphs in a holder

[polishookm]

When in

etoys-dev.image

I can open a halo on an EllipseMorph, click on the debug icon and then 
select "save morph in file." That puts a file, for example, grey.morph, 
assuming that's the name I gave to the morph, in my Squeak directory. 
The FillInTheBlank morph that assists with the naming process 
automatically appends ".morph" to the name I select, in this case "grey."

If I open a HolderMorph and put a few EllipseMorphs into it and if I 
open a halo on the HolderMorph and then try to save it in the same way, 
the dialogue box gives me the option to save the holder as a .project file.

When I try to bring that back into Squeak, it comes in as a something or 
other that takes over the World and can't be worked with in any way that 
I can determine.


So, my question is what's the best way to export a Holder with whatever 
objects it contains. The context is a student in my class has a holder 
with 57 or so sketches and we'd like to move it (the holder with the 
sketches) from from one image to another.

Thanks in advance,

Mark
