Bug: list filtering is acting on multiple lists at once

1) Standard TrunkImage, default preference settings.
2) Open a browser, select a class.
3) Select a method category.
4) Move mouse into methods list, but don't click.
5) Type a filter.

Both the category list (which has keyboard focus) AND the list under
the hand filtering simultaneously.

Cannot reproduce. The only thing that happens is that the selection in the category list might change due to the filter and hence the message list updates, too.

Best,
Marcel
