I'm running Motif 1.1 under HP-UX 7.05.

I've got a scrolled list widget created using XmCreateScrolledList
that I regenerate by doing on XmDeleteAllItems and adding the
new items using XmListAddItem(w, XmString, i+1).

If the list has enough items that  a scrollbar is required, one
appears. If I try to regenerate the list after I've moved the
scrollbar down even slightly, my application goes runaway. If I leave the
scrollbar in its initial position ( the top of the list is seen ), I have
no problems. Has anyone experienced similar problems ?? Here's a look
at my application after a kill -11.

Any help would be appreciated ..
