High everyone, my name's Josh, and I'm from Illinios.  I just started
using the latest distribution of Ubuntu along with Firefox 3 Beta 5
and the distributions of Orca and all other software that came with
the release.  I have noticed that Orca does not seem to be able to
read HTML text.  It seems to work fine with the latest Firefox, but in
Evolution, it won't.  Does anyone know how to fix this?  I have also
found that if I press the letter H to navigate to a heading, then give
Orca the command to read the entire document, it will only read the
heading title. Is there a way of correcting this?  Thanks a lot guys!
