Disposition: PROMPTFORWORD will change the cursor whenever it is called  (like Trillium does) -- thus the ringing of bells is a moot point, of value only when one isn''t watching the screen at all.  JonL, 8/2/84

Subject': can hang waiting for typein without RINGBELL'
To': LispSupport'
I said TEDIT(filename) and then buttoned another window and started working. I didn''t notice that the TEDIT was asking for a USER.CM in the prompt window. When I finally clicked in the prompt window, it did a RINGBELLS, so maybe it was hung up waiting for a monitor lock and never rang the bell.'
No quick hack solutions to this one, please, there is something fundamentally the matter.'

212': This is two problems.  (1) The ringbells "feature" in PROMPTFORWORD only is active while PROMPTFORWORD has the tty.  Personally, I would say this is not the problem, since I think the ringbells hack in PROMPTFORWORD is of dubious worth, and often an annoyance.  (2) Tedit prompts in an obscure place (the prompt window), far from the scene of the action.'

Bill, do you have some ideas about what this is about?'

PROMPTFORWORD has a "feature" whereby if you don''t type anything at it, then every 60 seconds it calls RINGBELLS.  This is implemented by a timer in its input character routine.  This routine, being a good citizen, calls \TTYBACKGROUND while it is idle, which has the side effect of blocking (until next bugged) if you take the tty process away from PROMPTFORWORD.'
(1) I hate this feature.  My understanding of why this feature is in there is because of calls to PROMPTFORWORD in the Promptwindow, which often go unnoticed.  [Side note': submit ar "Flush RINGBELLS from PROMPTFORWORD (or make it optional)"].'
(2) But given this feature, its behavior in your case is probably correct.  If you are typing at window x and suddenly the machine starts ringing a bell at you because you haven''t typed in window y, what are you supposed to make of it?  Flashing the window where the prompting is going on would make much more sense.'
(3) For this particular problem, the correct solution I think is for Tedit to do its prompting in or near its own window.  John says he is adding a promptwindow to Tedit (like Lafite), so this may already be done.'
