Odd, mine (4-Home) updates its display just fine, if I close the interface then re-open it.
I know if I do a manual update from the interface rather than from the icon menu, the version doesn't show correctly till the next time I open the interface, and I think the same's true for the last-scan info.
Hey, one more thought for the "Wish List", but I'm too lazy to post it there too -- how about some way to force a refresh of the status display under those circumstances?
