A pretty impressive explanation to me, better than I could have done.

I'll try Victor. When we think of screen reading, we assume that your screen reader (JAWS in this case), is literally reading text as it is written to the screen. While this works in many cases quite well, it is not the best solution for complex applications like excel or Word for instance. Fortunately for us, these complex applications were designed in such a way that they could talk to each other so to speak. So a document in Word, might be linked to a spread sheet in Excel so that a change in one can modify the other. A tool they use to do this is something called a "Document Object Model" or DOM. This is very robust and rich with information about everything in your document or spread sheet. Think of it like a really complete description of all the text, attributes, charts, tables, and so on. While this was not designed for purposes of communicating to Screen Readers, JAWS began to access the Document Object Model back in the 1990's as an approach to improve the opportunities that our users would be able to get a more powerful solution to all the advanced features of Office Apps. Other products have followed our approach in recent years and it has greatly improved their ability to work in these programs as well, compared to just reading the screen. Well, during such communications, if something goes wrong in the app while the screen reader is interacting with it, there is always a chance that we have not considered such an exception or interruption and we fail to gracefully remove ourselves from that process till things time out (or worse). That probably just confused you more, but from one non technical person to another, I did the best I could with it I think. Someone else could probably add or give a better example I'm sure.

What would cause Jaws or any other program to max out the CPU usage, thereby stalling Jaws? Could you please dumb it down for the uninitiated among us? Sheepish Grin.
