Hi Jim,
thanks for fixing the preferences bug in Tiger. But there is still a minor UI bug with the new 'sun' and 'moonlight' icons in the backgrounds tab (only Tiger, Leopard is all fine). It's just an optical glitch and doesn't seem to affect functionality. See the screenshot...
...and just in case you're running out of spots for polishing: I would prefer the solid white seconds hand of the analog clock i saw on the PC version...
Endie.
