<div dir="ltr">I was thinking about my last suggestion of the previous mail... I think we should look for a way to "simulate" Morph from Morph, for example using the simulation code that the debugger uses and run that simulation in a "controlled" fashion, a "morph simulation sandbox" or something like that.

Maybe for some cases, we could improve the situation. At least,
errors in #drawOn: should never crash the image. Not sure for other
methods, though. If you post a UserChanges file that results in this
behavior, I'll try to take a look.<br>

<div>I know that Juan uses the logs that are saved when an error
occurs (that is disabled in CuisUniversity just in case you
are using it, there is a preference to enable it).</div>
<div>It would be great to find a way to break the circularity
when doing this kind of thing. For example, if you want to
make changes in the debugger, the best way to do it is to
subclass it, work in the subclass so if an error occurs the
original debugger appears, and when finish push up the changes
to the debugger class, but I do not see how to do something
similar in Morph... maybe creating a new world with a
different hierarchy of morphs that are the one you are working
on?... or try to use a "stack of the morph framework" in the
same way some people work with a stack of compiler when
working with meta-circular languages?... </div>
<div>I'm sorry I can not provide concrete solutions but just
some ideas...</div>

<div>From time to time It happens to me that, for some

developing the image freezes.</div>

<div>When I reopen the image, I get to restore the changes,

<div>Is there a better way to debug this kind of situation?</div>
