I see that same behavior on linux. But not on Mac or Windows. Must be something about the way dialog boxes from Qt interact with the X11 window managers.

I have no idea how to fix the issue, but I do note that unless you have "persistent browser" enabled on the dicom browser it will go away when you exit the DICOM module. I suspect this is a good enough workaround for most uses?

Hi Steve,

I'm glad you could reproduce. When I enable "Browser persistent" I don't see the behavior you commented. Also, I guess that if the window is maximized it'll be difficult to switch to a different module.

I don't see a way to change this behavior without a re-write of the browser top level container (maybe make it not be a dialog on linux or something). Maybe someone who knows more about linux window managers can suggest something.

As-is the usability seems workable to me, even if not optimal: the window can be maximized/unmaximized as needed. And it is only visible in the DICOM module by default, but can be pinned to stay open with the "Browser persistent" option.

On further investigation I found this also was a problem with the Metadata dialog and there was no way to close it.

This adds close button to both widgets:
