there is PA_RunInMainProcess((PA_RunInMainProcessProcPtr)… which would run the
panel as modal dialog, that would be one possible approach I guess.
So I need to redesign my code and open the panel like this:
NSInteger result = [ panel runModal ];
Another would be to split the tasks, like open panel and get panel values and
close the thing, which would require to return a reference to the panel to 4D.
I have to think about that.

it just keeps the current 4D process away from doing anything.
