Hi Klaus and Markus,
I haven't posted much but I have been watching this thread and trying a bunch of code and I suspect that Markus is right: there is some kind of a flaw in the ExtendScript implementation. I tried SetProps as well and couldn't get it to work. If I get time, I will clean up my code and post it here and maybe you guys will get some ideas. But of course, if it is broken we might not be able to get it to work anyway.
Rick
