[gui-talk] Theoretical Question

[Dave Marthouse]

As I under stand it screen readers use hooks in the operating system to 
render the material on the screen readable with speech.  Knowing that, 
why do some screen readers work better than others with identical apps.  
Is it a matter of scripting or is there an inherent basic difference on 
how different readers work as far as their interface with the software 
used.  I'm academically curious.
