Re: [orca-list] Firefox caching

[Mike Reiser <blindguy21 gmail com>]

 I'll just chime in here and say that nvda on windows has a mode in 
it's virtual buffer that displays the page like orca does called screen 
layout.  If you turn this mode off it displays links one line at a time, 
can't this be put into orca as a compromise?
