"export image" issue

[Andrew Fazakerley]

if the "export image" window is open and sitting on top of the OVT main window, it is included in the exported image, obscuring part of the desired image. Can this be avoided please (so that one exports only the image in the main OVT window, whereever the user has placed the pop up window) ?
