Jaws freezing

Hi I'm using Jaws 11 with windows XP.  I'm having problems with Jaws on the 
internet.  When I'm on a webpage and am using my up or down arrow keys to move 
fast up and down a page for example, Jaws will suddenly stop talking, and won't 
re-start, not even when I go into the Jaws folder and sellect from there or use 
a short cut key.  It's happened a number of times today, and the only way round 
it is if I re-boot my laptop, which I know isn't good for  my hard drive.  I'm 
not sure what's caused this problem, but I have been getting error messages 
from Microsoft asking me if I'd like to send an error report, but it doesn't 
say what the error is or how I fix it.  Could the problem be net-based or 
something?  Any advice would be wellcome.  Thanks from Lori Duncan.
