Hi Kirk,
Recently upgraded to Windows 10 Home on a dual core 64-bit system. Running version 5, build 16438.
I've typically used the Preview view to scroll through a set of photos and mark and delete. However following the Win10 upgrade the delete command closes the Preview. It happens with either the toolbar icon or the Del key directly.
Thanks for all you do to keep PM the great product it is !
