Hi Efrat,
    We are using the BrowserDisplay actor in an example workflow in the 
Kepler Getting Started Guide (to display an image).  It turns out that 
there was a problem with it not recognizing the default browser on a 
Mac. I made some changes to the source to use some new open source code 
for launching any default Browser for Windows/Macs/Linux.

    The changes seem to work fine, but since the BrowserDisplay actor is 
a geon actor originally written by you, I thought I should ask if I 
'broke' anything GEON might be using the acror for !  (I hope not, but 
one never knows ;-)

    My changes have been checked into CVS and the lines I changed/added 
are marked with comments containing "Dan Higgins". Please let me know if 
I broke anything!


Christopher - I tried your suggestion of using the PT BrowserLauncher 
class and could not get it to open a *.PNG file (on Windows). The newer 
code at


seems to work, however. (I have used the Ptolemy launcher to successfully launch PDF, however!
