Hi Stefan,
You have wandered into deep waters, and I have no life preserver to toss
to you except the advice that it might be easier if you could reorganize
your Histogram functionality so that it doesn't have to launch dialogs from
your own frame. Failing that, you may need to extend JInternalFrame rather
than instantiating one.
regards,
Larry
