On the window title line, the minimize and close buttons have a mouse-over caption. However, I can't get the restore/maximize icon to show anything on mouse-over. Yes, this is a matter of consistency not function.
Is the behaviour different from any other application on Windows? (This is just a standard application window, so I'd be surprised if the tooltip behaviour was unique to Logos.)
Just tried Microsoft word. As you predicted, it has the same behavior - which is not the behavior Microsoft describes in its documentation for programmers. Thanks Bradley. You "fixed" that issue very quickly.
