	I'm writing to a scrolling text widget inside a scrolled
window and would like to keep the last lines written visible.  I saw
the recent FAQ question asking just this question:

>>Subject: 11) When I add text to a scrolling text widget how can I get the new
>>text to show?
>>
>>Answer: Use the call undocumented in Motif 1.0

But this does not work for me.  I still get the first lines of text
made visible.  
	I poked around inside the Motif code (TextIn.c) where I saw:

    XmTextShowPosition((Widget)tw, (XmTextPosition) -1);

Does -1 mean 1 character from the end of file?  Whatever it means, it
didn't work for me.
	I also tried using XmTextSetInsertionPosition() in combination
with the autoShowCursorPosition, which suggests it'll give me what I
want.  Again, no dice.
	Wanting the last text seems like such a basic need that I'm
surprised that it's not handled easily, preferably by some policy
setting.  Is there something I'm missing?
	I'm running on a sparc with X11R4, Motif 1.1.1, and SunOs 4.1.

	Thanks for any help.  Please send email rather than posting.
