Zoom not preserved

[davidh]

Sorry if I have missed some intermediate steps, but it is no longer posssible to preserve the zoom of one image after you click on another. If you click back on the zoomed image, it has already been restored to Zoom to fit.

I am aware of the left Alt key functionality to copy the zoom between images, but this is not what I mean.

This was accidentally introduced on 20-Feb when trying to fix another problem. I have removed the earlier fix for the next release.
