Try holding down shift and then right click on the world (or in a workspace execute: �World findWindow: nil.�). A �find window� pop-up should appear. Look through the PanelMorphs by selecting each one and the halo�s should appear. If you find the correct one then delete it and it should be removed.

As well as the suggestion there, you might also try...
SystemWindows allInstances [ :w | w delete ].

Hi there,

I often get in a situation where 'ghost windows' remain in the Pharo window (see screenshot).

These windows are closed (see taskbar) and I cannot select nor click these ghost windows to remove them.

Is there a way to remove them programmatically?

They cause visual clutter when working with multiple real windows and I do not want to rebuild an entire development image each time this occurs.

Though this is in Pharo3, I think I occassionally had these in Pharo1.4 as well.

cheers
