[nfbcs] USB window not opening

[Tracy Carcione]

It used to be, when I plugged a USB device into my PC, it would 
automatically open a window and ask me what I wanted to do:  play the music, 
view the pictures, view the files in Windows Explorer, take no action; that 
kind of thing.  Now, when I plug in a USB, nothing happens.  It makes the 
USB noise, and that's it.  I'd google the problem, but I'm not sure what to 
call it so I could find it.
How can I get my USB window back?
I'm using Windows XP, and Jaws 14.
Thanks.
