Blank wndows?

Im just setting up 9.5, started working on a project and noticed a bunch of blank windows (smaller, about the size of plugin windows) that will not go away when I click to dismiss them. Im thinking they may be from plugins that tried to load and failed from an imported project from earlier version that attempted to load and failed or perhaps help windows that can’t find their content. Any idea what they are and how to get rid of?

A picture would help understanding your case.
Also, when do they appear?

That’s weird, I swtched programs back to wavelab to take pic and now they’ve disappeared but I think they may be related to changing audio file name from clicking on its tab in audio editor.
