Not a big issue, but thought it worth mentioning.
When I set my "Main Controls" alignment to IBM they will sometimes
stick in the upper left hand portion of the stage, just underneath the
main menu. Usually a clearing of the cache and/or changing the
alignment, saving, then changing it back again fixes the issue.

If it doesn't stick, that's good! However you sometimes can still
see when loading the page how the controls start near the upper
left hand portion of the stage then reset themselves to the correct
location. (Try refreshing page several times over to see the 'effect')
Using Safari 3.1.2
UPDATE: This issue is a little more obvious in the most recent
update, "imagevue v2 beta 20080825." You can see the controls
clearly in the upper left hand corner when loading the page.
