Hi Everyone,

So, the new Cog VM has finally given me a reason to jump onto 4.1. I
downloaded Andreas' 4.1 Windows zip file, installed it on my robot,
and it starts up and runs with no issues.

I loaded my Brainbot server code from my Monticello repository, but
whenever I try and open any of my GUIs, the buttons are non-clickable.
In fact, I can't even bring up their halo - when I right click, it
switches between the system window and the alignment morph, but never
the buttons. If I explore the alignment morph, I can of course see all
the submorphs where they should be.

This code works in a 3.10.2 image, which is what I've been using up
until now.

I'm adding PluggableButtonMorph objects to an AlignmentMorph, which is
then added to a SystemWindowWithButton.

Has something about these things changed between 3.10.2 and 4.1?

Thanks,
Jon
