Opera will not open to full screen

  • I run Opera (latest update vers.68) in Windows 10 Pro. with dual monitor (extended option). I have Opera pinned to the taskbar and usually an additional shortcut on the desktop.

    I have had a re-occuring bug since Version 65. It re-occurs about every 3-6 months and shows in one of two ways. 1) when clicking on either icon the taskbar icon is underlined and shows a thumbnail but Opera will not open to full screen. 2) a second icon is generated on the taskbar but behaves as in 1) above. the second icon disappears when close window is selected.

    I have found that I can correct this by unpinning the taskbar icon, then deleting the desktop shortcut. Go to the Opera launcher location - for me this is C:\Program Files\Opera\launcher.exe (check- Help|about opera-Paths)
    Right click on launcher.exe and pin to taskbar. If required, right click and create shortcut & drag this to the desktop.

    I cannot duplicate the problem after curing it to attempt to find out why this happens, so I hope the above may help.
