Hot key to 'restore or minimize main window' ... It now "works", (sort of). It's only half-way fixed, because when the window is restored, it does not restore to the top. It restores UNDER whatever application is open, (such as a browser). This is definitely problematic and a time wasting inconvenience. So for the moment, the 'hot key' is a 'luke-warm key' at best. Hopefully this can be resolved soon.
