Re: [g-a-devel] AT-SPI table interface problems

[Bill Haneman <Bill Haneman Sun COM>]

Hi Pete

These sound like bugs.  Of course, operator error is another 
possibility, but in any case we can't determine what to do without bug 
reports, test cases, etc.

FWIW, I don't see these sorts of problems with at-poke, and gnopernicus 
has not encountered them, so it's possible that you have inadvertantly 
wandered into unexplored regions of the gtk+ treeview implementation.
