@sgunhouse Then how do you unlock it? Though I went through all the setting and found no lock on wallpapers and I have the latest version (60-) of Opera. I am not having this problem on my Laptop only my gaming desktop.

I installed the Sun animated wallpaper on to Opera but the wallpaper disappears after I close the browser. I have to reinstall every time I start up Opera. This is also only happening on my Gaming computer not my Laptop. Both have the latest version of Opera (60). This problem still happened on the older versions. Any Suggestions?
