Sometimes I forget what it's like to be a newbie, too, but sheesh!  :-)
(pardon me if you're not so new, Stephen, I haven't been reading  
squeak-dev extremely closely)

In case "edit the code" wasn't enough of a hint, here's how I figured  
it out:

- browse to SystemWindow
- with the 'inst var defs...' menu item, find all of the places that  
the 'borderWidth' instance variable is set
- hmm, #borderInitialize looks promising, so browse to it
- see that the initial value is defined by #defaultBorderWidth
- override the implementation of #defaultBorderWidth, and you're done!
- open a browser to test it out

Rats!  It didn't work.  OK, let's debug...

- inspect the result of 'SystemWindow new' in a workspace.  Yep,  
borderWidth didn't change.  Why not?
- highlight the expression again and choose the 'debug it' menu item
- step into the expression and see that the first message sent is  
#hasPrototype.  Sounds suspicious!
- select 'self' in the lower-left debugger pane, and choose 'inst var  
defs...' from the menu to see who defines 'prototype'
- there's a prototype message; let's clear the prototype with:  
'SystemWindow prototype: nil'

Now it will surely work!  But it doesn't.  To make a medium-length  
story short, SystemWindow>>initialize stomps on the value that had  
been properly set by the superclass.

I suppose that this is because I didn't load LookEnhancements first;  
otherwise, the above would probably work.  But I don't care enough to  
try.  BTW, this is in a Croquet image that's basically 3.8 as far as  
Morphic is concerned.

Anyway, I guess I've shown that it's not completely trivial.  Even if  
I had loaded LookEnhancements first, it seems likely that the  
prototype problem would have arisen.  Hopefully someone learned  
something about Squeak debugging.

Cheers,
Josh
