Let's say I copy a PNG from the web and it has a transparent background. When I paste into Fireworks the transparent background is replaced with a black background. Is there any way to prevent the black background from appearing?
I had a theory about black being used as the 'transparency colour' for those particular images (I use a bright green). However, I tried replicating the problem in Fireworks 8 on one of my own images, and I got the same problem.
Turns out whoisgregg is right on the money. Save the images somewhere first, then open them in Fireworks. Copying and pasting inexplicably makes the transparency black and un-transparent.
