Yes, you can use SiRFDemo 3.81 (Copyright © 2005 SiRF Technology, Inc) with 
JAWS and get the job done. The best way to go is to start in random mode 
with no receiver attached, to get a feel of the layout and the menu's. 
However, it's not a 'trial and error' sort of program. You can render a 
receiver useless by disconnecting in SiRF mode, the program will not issue 
any warnings. The menu's are accessible, the graphics in the toolbar can be 
labeled and the JAWS cursor gives you a good view. I've gott the manual 
that came with V2.x and a 'how to switch off Static Navigation' document 
and will include that in the package. All previous warnings still apply!
