Hi Micha, I guess for the automatic version to work you would need some different behavior for the Rhino _run command.

You'd want a version that ran the program and also waited for that program to exit before it let Rhino continue on normally.

You might want to ask in the Rhino newsgroup if anyone out there has developed a plugin to do that task already.

If not, that may be a good enhancement request for the regular Rhino _run command to be able to take an optional scriptable "WaitForExit=true" or something like that.
