PS - Bug/RFE logged here:
If there are other specific problems that people know about, I really
encourage them to log bugs. Otherwise, the team will likely not know
about them and they will likely go unfixed. The current AT-SPI
maintainer, Li Yuan, is *very* good and is remarkable in his abilities
to diagnose and resolve problems.
