Rick, whether this feature ever works with IE is very much up in the air. I have no Windows computers in this house so making it work with IE is extremely difficult for me, especially considering how bad of a browser that is. But I know a lot of people don't have a choice... It's something that stays in the back of my mind all the time.
2) Probably the same as #1 for me. I never experience that behavior in all the browsers I access the site with.
3) Yes, certainly. Once this is ready for prime-time, there will be a tab up top for it.
