Problem with accessing the windows (OS X)

[bnspy]

I use version 6.10 with OS X 10.9.5.

when there are different windows of FreeFileSync open (main window, progress window, ... ), I have problems to access the windows that are hidden (i.e. if you klick on the main window, or if an FreeFileSync alert window opens, the progress window is hidden behind the main window ... or even deeper). There is no windows menu in the menu bar. Is there any other method of getting a window to the foreground than shifting the windows around and clicking on the hidden one?

After FreeFileSync has finished, it is important to close the progress window before the main window, as otherwise FreeFileSync crashes.
