In the recent large changes to Morphic I introduced an unrelated bug
that wouldn't be apparent until saving and restarting the image. I
just pushed a fix to GitHub.<br>
<br>
I tested a bit, and I hope it is ok now.<br>
<br>
Thanks for reporting!<br>

<div bgcolor="#ffffff"> Wow. I think there was a random
process scheduling bug. It worked OK if installing updates
from another starting point (I don't even remember which),
but not if starting from #4322.<br>
<br>
I just pushed a new version of update #4342. The fix was to
add a Delay after spawning the new Morphic process, to give
it time to be setup before interrupting it. It seems to work
now. Please try it.<br>
<br>
Thanks, Phil!<br>

Hi Phil,<br>
<br>
For most people, the general advice is to
just use a new, updated image from the repo.
In general, I think that keeping own work
separate from the image, and loading it
every day, is the best workflow. It works
for me.<br>
<br>
Still, if you want to update your personal
image, use the FileList to take a look at
update #4342. See what it does. It does only
what it says: It removes an unused ivar from
HandMorph. Just not applying this update
will not have serious consequences. This can
be done by editing the doIt in the
changeset. In your image, HandMorph will
still have an unused ivar. It is not a big
deal.<br>
<br>
Another alternative, of course, is to debug
the problem. Extract the doit from the
changeset. Evaluate it in a Workspace. If it
crashes, repeat with smaller parts. Can you
fork a process that just sets a global
variable? If so, can you make it print to
Transcript. (This is an extremely useful
technique when messing with Morphic itself,
that's why we have a Transcript that runs
independent of Morphic). Ok. Can you stop
the Morphic process and start a new one? Can
you redefine class HandMorph with the same
definition as it has today? And so on. Part
of what comes with the personal mastery of
your own image is this. Its problems are
also yours!<br>
<br>
If all this fails, you can make your image
available to me and I'll take a look.<br>
<br>
Cheers,<br>
