Hi Hugh,
Good suggestion -- and along the same lines I was thinking :)
I'm planning on investigating the appearance code in more detail when I next
have a few hours to dedicate to it.
Thanks,
Simon

That's very interesting. When looking through the code for the default
appearance (see the message I posted yesterday - search on "fontObject") I
found that colorObject and borderObjects were being used. These explicitly hold
references to the widgets that they are associated with, so they can be updated
if the color changes. It seems pointless using them in the appearance when the
appearance itself is unlikely to change - you apply a complete new appearance,
all at once. I'm guessing that the appearance code causes the association to be
made.
Perhaps you could try rewriting the default appearance to not use the xxxObject
form of these items. That might remove the circular link. Or make sure that the
widgets are removed properly from the objects.
This is just educated supposition - I haven't had time to trace all the code
yet.
Hugh
