Bob,
Thanks for the reply.

All I've tried is simply 'viewer.scriptWait(command)' in a block
of otherwise functioning, thread-naive, java code. This causes the app
to hang
indefinitely on this line.
'viewer.script(command)' in the same
place works OK, provided this is the only command I need
to issue, as described.
Do I need to do something special to the viewer.scriptWait() in order to
wait on it?
I am pretty much ignorant about threads in any language, particularly
java.
Thanks,
Dave
