Commands that are executed in the Desktop Mode will hide the OSD if launched from a fullscreen session, though music playback or other functions will remain active in the background. The OSD will become visible again as soon as the application in question quits, and you will be returned to the Commands Menu. The only exception is the Web Browser. If it’s launched from the Main Menu, it will also return to the same location afterwards.
To prevent the OSD from being hidden while another application is active in the Desktop Mode, press the OSD FScreen button on the remote control (UMP-R-1XX) or the ‘z’ key on the keyboard (UMP-R-2XX, UMP-R-3XX). This will change the OSD to the windowed mode and allow other applications to be displayed beneath and on top of it. When the OSD is in the windowed mode, the TitleBar is displayed at the top of the screen, which allows you to minimize or close the OSD, too.
To resume the fullscreen operation of the OSD, press the OSD FScreen button again so that the TitleBar is removed. Please note that the OSD must be focused for the FScreen button to take effect. In other applications, this button will generally represent the character ‘z’.
