When restoring, the windows titled "Restore" appears with the command used to restore selected files and folders. It seems to be a non-interactive terminal emulator window.
The close button on the bottom right of that windows has a "Close" button on the bottom right of the window, it's disabled while the command in running so that the command keeps running, but the window manager's close button is still active, clickable, and able close the window which kills that window (probably the commands too) and freezes backintime-qt
I know you can just disable/remove window manager's close button for that specific window, so I suggest it should be disabled/removed, to prevent accidental data loss. A simple change
