Issue description:
Hey guys! I was using Pixelorama at work on my extra monitor (i have a laptop), once i finished using it, i closed it and later opened it again but without using this extra monitor but something happened (or didn't).

After the splash screen, i could not see the window and neither close it normally, needed to use the Task Manager.

Even if i focus on the program on task bar, i couldn't move the window around using Alt + Arrows like i'd normally do, it was annoying.

I can't test on my linux desktop at home because i don't have an external monitor, but you guys could and say if it happens there too.

I've already checked out the source code and made a small change that could fix it, at least i tried and it worked.

I'm opening a pull request along with this issue.

Thanks in advance, this tool is great!

Steps to reproduce:

1. Open the program
2. Move it to an external monitor
3. Close the program
4. Disconnect the external monitor
5. Try to open the program again and voila!
