I'm not sure if this is what is being experience by others with the screen persistence but this is what happens to me and I don't think it's a bug. I think it's a feature of the dual display card remembering it's last setting.
When I unpack my laptop at home I don't hook up a second screen (TV monitor). When I play a song the laptop viewing area becomes the lyrics display (full screen), this is normal. I double click the lyrics screen and resize to a small screen in a lower corner as described in the manual.
Now when I fire up Hoster at my next gig, with dual screens, after the first song has played the singers screen is black and blank. The blank screen is an empty lyrics screen, no wallpaper displayed. I have to move my cursor to the blank screen and drag it to my laptop screen where I resize it and move it to the lower right corner. I do this one time and now the singers screen displays the wallpaper after each song has finished. This setting remains persistent from one gig to the next as long as I don't start Hoster in single display mode.
Could this be what others are experiencing?
If not, please excuse the ramblings of an old KJ
