I noticed a very little difference when I watched The Empire Strikes Back - The Special Edition on VHS recently. The blinking red light on the top of one of the buildings behind Boba Fett's ship on Cloud City (which is a wonderful little detail) was not to be seen. I'm so used to seeing it on the Original version so I noticed this little difference immediately, I have checked the 2004 DVD version and it's not there either. Is this just a -97 alteration or could it be a left-over from a 70mm print? I'm asking this because it would be strange to omit this little detail on an otherwise untouched scene.
I'm sorry I didn't have some pictures to show the difference.
