Alright, this should now be fixed. Actually, this also fixes a problem
that I've seen with the STE demo "Pacemaker" in the past - there were
graphical glitches in the endpart scroller when the demo has been
started from a GEMDOS HD folder. Thanks again for the hint with
Pexec(7) ... that was the missing piece here.
