Here is a scenario that shows how the resources updated tag on the top right of the Home Page can be misleading:
I have Verbum open - an update comes down. Say it now says "6 resources updated x". Great. I check them out, maybe tag them, do what I like to do to review new resources, and then I go to the Home Page and click the x to remove that notification.
Later in the day, I receive an email that a prepub of 10 resources is now available. Without closing Verbum, I do "Update resources", and go back to work. Later I check, and it now says "16 resources updated x". Whoa! Must have gotten something else! But when I check for new downloads, it is only the 10 - it is re-reporting the original 6 that came down, and that I acknowledged/closed-cleared the notice.
I think once you acknowledge the notice of a particular number of resources being downloaded, it should not report on them any more.
