	I'm having mucho problems with the interactions between the
Athena Widgets and the xview programs when it relates to cut & paste.
The Xaw, uses the primary selection: the left mouse button selects
and the selection is put in the primary buffer.
	But what do the xview programs use?  Their select has
the same behavior so going from xview -> Xaw is easy.  But where
do the selections go when you press "Copy" or "Cut"?  Following
the suggestion from Ridge McGhee, I tried using xcutsel.  Without
more informations than this I succeeded in pasting text from
Xaw -> xview by: using one xcutsel to copy the PRIMARY to buffer0
and one xcutsel to copy from buffer0 to the SECONDARY and then
paste to the xview application with the "paste" key.
	BUT it only works for ONE paste, doing two in a row
with "mail" in the buffer gives: "mail^@^@^@^D" (Sparring you
from the actual control characters).  From now on, cut and paste
within that xview application will never work!  It will always paste
"^@^@^@^D".  There is definite correlation between the length
of the strings.  Starting a new xview applications (eg: mailtool)
has no effect.  One more piece of information is that the
"copy 0 to SECONDARY" button of xcutsel stays activated during
this time (it stays the owner).  Doing a further use of
xcutsel works so now I have the following working:
	Xview -> Xaw
	Xaw -> Xview
but not Xview -> Xview !!!

      	So how to I make Xaw and Xview talk to each other?
Anybody from Sun cares to comment?  I don't think it is a
good reflection on the product if it doesn't talk to the
rest of the world and even worse I haven't found any
documentation on this particular problem.
