Desktop Client: Repositories menu commands not available if Repositories window is unpinned
If you select (highlight) an item in the Repositories window, unpin (hide, collapse) the window, and then go to the Repositories menu, you will find that commands in the Repositories menu are grayed (greyed) out.
This is intended behavior to avoid unsafe situations, since the Repositories explorer window rolls up (hides) when Repositories menu is clicked and you cannot see which repository item you are going to perform the Repositories menu command upon.
Please remember that when the Repositories window is unpinned and collapsed, you may simply hover over the collapsed window to redisplay it, and then right-click on an item to choose one of the many Repositories menu commands that are available in the pop-up context menu for that item.
