Hi.
I use Eagle 7.5. I noticed that sometimes all Eagle's windows just disappear, when I'm not looking. I don't know what are exact reproduction steps, but:
- I use KDE/Plasma 5
- I use external monitor, sometimes plug it in, sometimes plug it out from my notebook
- I have Eagle running, I plug-in the external monitor
- I lock the screen, and go back to the computer eg. after an hour
- All Eagle's windows (control panel window, schematics window, pcb window) are gone
- Eagle's still running in the background (it's in the processes list)
When I try to run Eagle again it tells me my project is locked. I do `killall -TERM eagle` then run Eagle again and "delete lock".
I haven't had problems with it, since I regularly save my projects, but I guess it might be something you'd want to fix. ;-)
