Hi Bill,
thanks you very much for the nice reply.
I followed the link you send using firefox or safari (java 1.6, mac os
x, 10.5.8), but I was not able to run any of the movies you link to.
ImageJ opens via Java Web Start, but without any data. That makes me
think, that maybe something in the configuration of my local system is
not right. on a different machine I got an error message stating, that
"this macro needs 32bit Java" which makes sense, because both machines
are running 64bit Javas and I know that the movie player (Quicktime) in
ImageJ only works on 32bit-systems. therefore ,if you use the movie
player, the web start including a movie can not work on 64bit-systems,
which still is a pity.

Principally I like the idea of dynamically written macros called by an
autorun-macro. Would you mind to share some code? Maybe I can modify it
to my needs. I just need to open jpgs. that should be possible with the
construct you are using.

Thanks,
aRnim
