Hi Roy, Marsha and all,
Jack is almost right when he mentioned something about processor priority and
the task at hand. True, some applications seem very busy, others want priority
no matter what. Hey, we're supposed to be in a multi-tasking environment with
free input. Okay, let's have another look at the web page download situation
from a programmer's point of view: We have three main players: the Operating
System, Internet Explorer, and Jaws 6. Normally, Windows acts as a referee or a
moderator, sometimes. You can call the Windows Task Manager using Alt Control
Delete whenever you want to end a responding or non-responding task, but it
doesn't always work. Internet Explorer alone will let you use the Escape key
to cancel a page download if you change your mind, and if there's no hacker
capturing your computer. This is very important because the Escape key has to
be accessible in any situation. Normally, this Escape key alone should stop any
speech output. Jaws has a complex task: it has to monitor the user input
(keyboard and mouse) as well as Windows and application processes all the time,
not matter what. Not always easy! Applications have to act in a civilized
manner, that is to say, do your thing as much as you want, but let others do
their own business via the Operating System, whenever they want, if and when
required. Not an easy task! Normally, programmers will design a process such as
reading or printing, or whatever, but it's better to keep the communication
open so that other applications can listen to user keystrokes for their own
business. That's not always the case. You can have a hit and run situation, an
application forcing you to react through some dialog boxes, or worst, an
application will hijack and freeze any user keystroke in the system in order to
do its own thing. To summarize, the Escape key provided by the Windows
Multitasking System should stop any web page download at will, and the Jaws
assigned Control key should stop any speech output whenever pressed. If nothing
works at all, then we have a synchronization or a design problem.

Hi
I have noticed that jaws does not shut up when it is reading a web page
article. Enough is enough, but it still goes on. LOL
