SL3 issue: "Zoom Picture" is adding a grey border around the image

That is really a shame. We use - and pay -  Articulate because it is supposed to be an authoring tool, helping use to do what we want to do the way it is supposed to work. Not to do some workaround again and again. If you don't really support a functionnality anymore, you can try, I dont know... to remove it from the tool? Or de-activate it until it really works again? Or give the infos Ryal gave upthere: it only works with .png files with transparent background?
It's really a shame how long everything takes so long to get fix here.
