Hi Andreas,

  I cannot reproduce this on my system. What I tried:

run guitest, in dialog [tab3] start histogram filling and whie
filling resize title, resize stats box, move histogram frame. Stop
filling, do the same. In all those cases I do not get any X11 error.

Are you displaying on a remote display? Do you use an X-terminal?

Cheers, Fons.
