I don't understand what I'm doing wrong. I have an edit field with a grouped
scroll bar created in PG. If the field is not scrolled back to the top, and I
use TESETTEXT to change the text in the field, the area in the window above
the edit field sometimes gets erased, even if I offset the view and
destination rectangles of the edit record way off the window before changing
the text. Even if I scroll the text back before changing it, as below. Does
anybody know why that would happen and what I should do about it? Thanks.

CALL OFFSETRECT(#([teh&] + _teViewRect),5000,5000)
CALL OFFSETRECT(#([teh&] + _teDestRect),5000,5000)
CALL TEPINSCROLL(0,5000,teh&)
CALL SETCTLVALUE(BUTTON&(_scrlBar9WClass1),0)
CALL TESETTEXT (knotP&,knotLen&,teh&)
'window area is now erased???!!!
