Sprite Editor "dialogs" left behind when Sprite Editor closed

After using the Sprite Editor to automatically slice up an image, this is always left behind:

I can’t make it go away without restarting the editor. -no-throttle-updates doesn’t resolve it, either. Is there a workaround for this?

Hi,

As a workaround, select the window that was left behind, with the mouse, and press Alt-F4.

Cheers,
Mark

Thanks Mark,

Worked perfectly.
