I have the newest version (2020) and sometimes I will click the icon and it won’t open! I view running processes but it isn’t noted. I have tried to open it over and over again to no avail. At times my “stage” screen will be overtaking all of my background etc. on my computer and I cannot see my mouse (still nothing in processes).

I tried to uninstall and reinstall BUT the uninstaller says it is running and to close it… still nothing within “processes”

It’s the weirdest thing. Any suggestions?

I have discovered that if you have marked the control panel to output 2 and do not have a second display the next time you open the app this occurs. I had to download “windows process explorer” to find the java which was background running and held the quelea information in it. I quit that process then attached my second screen, reopened and change the settings. Fixed
