Desktop Icon looks different from the original .ico
I have just started using RealWorld Icon Editor 2010.1 (trial version). I downloaded the 64-bit version because I am running Windows Pro 64-Bit. I have created a new .ico from a .png file and put the new .ico file on the desktop. This icon appears fine. But when I select this .ico as the new icon for any other shortcut or folder on my desktop, it does not look the same as the .ico. It looks like a low quality version. I re-edited the new ico, and removed all 'Images' except for 256x256 pixels, smooth edges. But this has not helped.
I have noticed that the way the .ico looks on my desktop is identical to the preview in the Images pane, but when I apply this ico to another folder, it appears like the 'Layers' image in RW Icon Editor.
I am having the same problem with other .ico files that I have just made.
Thanks for any help.
