Hi Paul, I just took one of my old transparent .png images that I used to use a couple of years ago and imported it as a control into an LC 8.1.3 stack. It worked just fine.
I think I might have created it with “Graphic Converter” for Mac. If you put one of your images into a “DropBox” account with a link for me I could take a look at it for you, and see if I can find anything wrong with it.
