Hi Christopher,
I applied this patch manually and it works now. My problem occurred, because
the patch is not merged into:
https://source.eecs.berkeley.edu/svn/chess/ptII/branches/kepler-2-3/ptolemy/actor/gui
And apparently, this is what my Kepler-2.3 from release branch uses.
Can the changes be merged there?
Regards,
Tomek
