[timothyhobbs seznam cz]

Warning.
A reacent bugfix in the package brltty on arch linux will bring complications to braille only users.  This is 
a security fix that creates a new user group brlapi.  You must add your user to this group in order for orca 
to function with brltty.

# usermod -G brlapi,audio <username>

in place of audio, list any groups allready given by the command:

# groups <username>

after having updated brltty and added yourself to the brlapi group, logging out and back in again should 
return things to normal.

Sorry for the inconvenience,

Timothy Hobbs
