[kepler-dev] Kepler won't start for me...

[Edward A. Lee]

Kepler won't start for me... I get the following
exception (BTW, this sort of experience has convinced me that
this idea of loading all the actors at startup time was a really
bad idea, and in fact could ultimately make Kepler unusable...
Can I talk you into going back to the Ptolemy II model of loading
actors only when the libraries are opened?).

Any suggestions for starting Kepler?  I tried deleting the lock
file, but the OS won't let me, telling me some other application
is using it.  I suspect the other application is Kepler, left
over from a previous failed attempt to start it...
