Let's say I have a floating window with three tabs. I want to drag a book showing in my library window to my floating window to become another tab. It works—except most of the time when it doesn't. I have to get the new tab lined up just precisely perfect which seems to be an almost impossible thing to do. That little black bar comes and goes so quickly that sometimes it takes 20 or 30 tries to actually get it dragged. This is a serious productivity killer. Is this a logos problem that can be fixed, or is there an adjustment I need to make in my computer somewhere?
