Re: [orca-list] Emacs and Orca again

[Willie Walker <William Walker Sun COM>]

Hi All:

This is also not an Orca-specific problem.  The problem exists when  
accessibility is enabled, regardless of whether assistive technologies  
are running or not.

As I mentioned in  
http://mail.gnome.org/archives/orca-list/2009-August/msg00124.html, my  
guess is that the root cause of the problem might be some odd main loop  
reentrancy issue inside emacs-gtk itself.  On my OpenSolaris box, the  
hang really only exists when I run accerciser and is more of an  
unacceptable long-ish painful delay when running Orca.

While this is not an Orca-specific problem per se, however, I think  
it's fair to at least come up with a workaround here to get people who  
use emacs and Orca off the ground.
