Hi everyone, the reason the hourglass doesn't disappear, is because it's actually a reminder to refresh. Here is the selection out of the article mentioned by MCITP: Updating a collection membership list does not automatically refresh the view of the collection in the details pane of the SMS Administrator console. Instead, an hourglass appears next to the name of the collection in the console tree as a reminder to refresh the view. To refresh the view of an updated collection, select the collection and press F5. I admit that it's a bit confusing since an hourglass has always meant that we had to wait for something, but everything's easy if you know how to do it right? Greetz, MrPatch.
