I have found that when I make a post with a URL and then go back to edit that post, when I click the save checkmark and expect my changes to save and exit the edit window, it does not. I have to click the checkmark first then click the "X" to have a pop up ask if I want to discard my changes. Once I accept, the edit window is closed and my post shows with the changes. This seems to be a MS issue. It only does this on URL posts, when I edit a text post, no issues, save works as expected.
