Auto-complete may be working better now, both on the reader pick list and in the author pick lists.

I don't know if this will fix the "flash then disappear" bug that was so annoying. That bug wasn't reproducible in the development area.
Also, instead of getting the spinny-thing which made the "focus" shift out of the box (so that we had to click back in the box to add/remove letters), the spinny-thing is gone. So you stay in the box.
And, All Links in the Magic Window now are forced to open in a new tab/window. No more telling people to Ctrl-click their name, and no more need for "target=_blank" in html links in the Notes field.
YAY!
