Thanks, Bob,
I agree that the "document title" report is better than the console, and I
didn't know about it.
But I still insist that we need something one can't miss. The document
title report mechanism means I have to stare at the document title while
I'm running scripts. I can still miss an error if I am absorbed in script
development. The fact that I didn't know about the document title report
says it all!
I still argue that we need an alert that "you can't miss", even when you're
not thinking about errors or looking for them.
Netscape 4.x has a setting that opens an alert popup when a javascript
error occurs. This is fantastically useful. MSIE does the same, although
its error report is nearly useless -- but at least you know there is an
error. I have not found how to trigger these kinds of "can't miss" alerts
in Gecko browsers (Firefox) and this is a serious disadvantage in my work.
I have to manually open the javascript console, and watch it for errors --
a situation rather like the Jmol console and not at all satisfactory. I'm
sure I've missed some.

I think we need a mechanism in the applet to alert developers when a
script error occurs -- an alert that cannot be overlooked.
This is certainly something I've worried about. What if when you use
set debugscript on
and you are using the applet interface, error messages are also recorded
in the DOCUMENT TITLE at the top of the page? I've been doing this with
some of my pages, and it seems to work well. This, it seems to me fits the
bill, because it is unobtrusive, obviously for the developer (because
debugscript is on), and can't be missed. Because it is a single line, it
only records the particular error you are interested in.
