This is the first time to use the forum, please overlook my clumsiness. For some reason , if I open say, Firefox, on my second monitor and walk away for an extend amount of time and come back, Firefox is now on the primary monitor. Although is a small thing, it is still frustrating. I have searched for settings that control this "feature", I have been unsuccessful. One other problem (although minor) , in the evening I turn the monitors off (the computer remains on), when the monitors are turned on again, you guessed it, everything is back on the primary monitor. Thank you for any assistance to keep my sanity.
