When viewing pictures by double clicking them is it possible to go to previous/ next image with the scroll wheel or using backspace/space. After copying the image (Ctrl-Y) the scroll wheel and space/backspace no longer works.
Not sure why it happens but if, after doing the Ctrl-Y, you click another window and then back to the viewer the mousewheel works again.
You'll fix it - right ? 
I can't fix anything, I don't work for GPSoftware or have access to the source code. 
Hopefully someone who does is reading here but if you want it fixed for sure you should report it officially using the form here:
As it says in the list of forums, these forums are just for user-to-user discussion and support, although people from GPSoftware do join in sometimes as well.
Thanks for pointing out.
