Hello,
 
I have found some answers and code samples in groups's archive.
Running two worker queues - one for command evals and the other for keeping return values worked like a charm. Originally posted by Johan Lindstrom and Blair Sutton.

Works as PL and EXE without visible GUI degradation while minimizing, overlapping, restoring, etc..
 
Thanks,
Igor.
