I had multiple screen shots done (first pop up windows not closed) and one of them open in the editor.
When I closed the editor windows, I got asked if I wanna safe it (I clocked on NO, I coppied it already to were I needed it) and all windows got closed together.

Also the just captured and not yet edited screen shots gets closed!

I just wanted to close the editor screen, not all the other screen shots as well!

If I take another new screen shot, then out of nowhere the old screen shots appear again.

Please make sure when closing one windows, the others remain open and do not closed as well
