'
	Our EMACS seems to have developed a strange problem lately that'
nobody can explain (there are no apparent software changes)':'
'
	Over an Interlisp-D CHAT connection, EMACS is not responding to'
cursor positioning commands sent by the mouse.  For example, the mouse'
would say C-U 4 C-F and the cursor would just stay still.  If you'
refresh the screen with a ^L you *will* find the cursor in the correct'
place.  If you type the command by hand it works!  We have determined'
that EMACS *is* seeing the commands (via ^_L) but is *not* sending'
cursor positioning back to the NVT (running EMACS under PHOTO.)  It'
*did* work about two weeks ago just fine but is not working now.  Does'
anyone have any possible explaination?'

						Jeff'
P.S.  The particulars are':'
	The CHAT program emulates a DM2500'
	We are using EMACS version 162 on a DEC-20'
