This is opening an image saved via SuperPNG using File->Open As. If I just open it normally (either Open, or by dragging into PS) then PS uses its default PNG importer and it works fine. However, the reason I installed SuperPNG (which I used to use years ago--thanks for it!!) is because SuperPNG imports transparency as alpha.
Is this a known issue with a known fix? I googled a bunch and didn't see any hits. Opening a PNG saved via SuperPNG without Alpha works fine.
