Hello again!

Now for something completely different :)
I want start a process from my BETA program and let it run concurrent with
it.
The BETA program shows a window which contains a Cancel-button which should
cancel the process initiated by the program.
That is not the problem. If the external process has finished normally the
BETA program should go on with the normal program, i.e. the normal flow of
the program itself.
So I can use myProcess.awaitStopped in the program, which freezes the BETA
program's window, so that the Cancel-button cannot be used.
If I use concurrency via fork, where the forked process awaits the initiated
process to stop, although the forked process is NOT my "normal" program, the
program also freezes.
So I can see no possibility to let both parts run concurrent without any of
the parts freezing.

Any help is appreciated. Thanks in advance.

Regards,
S. Kimmel
