Re: [orca-list] keys in conflict with XUL application keys

After more testing, the Orca patch appeared to have some problems.  It
throws occasional tracebacks and it doesn't speak in some of the Firefox
UI elements, for instance in the file dialog invoked by Ctrl-O or in the
Quit confirmation dialog (when multiple tabs are present).  The
following tracebacks are thrown when the Quit confirmation dialog is
opened:

Without the patch, Orca works fine in the mentioned situations.
