BTW - one other issue with the early access release of 1.7 for Mac OS X.
ptolemy/actor/gui/BrowserLauncher.java was failing under Mac OS X:

Hi Christopher,
Thanks for the fix. I agree with you that it'd be good to fix the ptII

I can use Listen to Actor for Kepler 2.3 on Mac OS X, but not under
Windows. When I select the option from the context menu, nothing
happens.
Also, when I try to edit a script for the Python actor, I get an error
message Failed to open a dialog to edit the target (null) - this
doesn't bother me
