I think she is talking about the standalone settings dialog Klaus, and certainly that could pose a problem if it somehow was in back of the top menu bar (not sure how it would get there, but I could see it happening).
On Linux, you could simply hold your alt key and move the window by grabbing any part of it, on Windows you can do something similar by the right click menu on the taskbar icon for the window, but I am unfortunately not aware of the 'Mac' way to do the same, sorry
