Taskbar preview shows all previously opened selector windows

[vrad-exe]

When hovering over BEE2.4 in the taskbar, every selector window that the user has opened since starting the app will be shown in the preview. They aren't actually open, and disappear the moment you click on the app to un-minimize it. I'm not sure if this is something that's fixable, but I haven't seen it reported yet so I don't know for certain.
