Summary: gop multiplicity

Initial Comment:

1. Open patch.pd
2. Delete the subpatch.
3. Either a) create a new my_abs object or b) undo the previous delete
4. Repeat steps 2-3 n times.

Now when you open the subpatch, all actions occur n+1 times, e.g.:
* creating a new object box makes a chain of n+1 object boxes
* patch is saved n+1 times
* paste creates n+1 new copies

If you don't save and try to close patch.pd, it repeats the message "discard changes to patch.pd" and sometimes crashes after two or three times.

The behavior persists until closing pd completely.  So if you go through the steps above 3 times, close the patch, and reopen it and go through them 3 more times, you'll get 7 extra objects every time you create something from the "put" menu.

I only get this behavior when using gop, and with an object visible in the gop window.  Same for abstractions.  For each extra object created in the subpatch, I get a "consistency check failed: canvas_vis" error to the console.

I confirm I can 100% reproduce it on Windows Vista with 0.42-4.
Unfortunately I am only a user so I cannot help.

I have also encountered the same problem; my patch is too big and complex
to attach it, but in my case I can reproduce the problem by just:
A - loading the main patch
B - closing it
C - loading it again
And I get the "mulyiplicity" in the main patch, not any subpatch.
But not with your patch.

I forgot to say I'm using winxp sp3 with pd vanille 0.42-5 to produce the
behavior in the attached patch

In step #3 above, please ignore "a) create a new my_abs object" and simply
undo the previous deletion of the subpatch.  Also, the multiplicity bug
happens only within the subpatch window.
