There's no need to interlace, and most applications should determine the

best compression method for you. I don't have Photoshop handy on this

machine right now and so can't check, but I do recall posts from people in

the past who have used its PNG without incident.


These days I use Fireworks most frequently. Its PNG comes into Flash 3

nicely, and the alpha-transparency is particularly useful. (You can use the

alpha in PNG as a mask on vector shapes in Flash 3.)


Now, on these particular PNG, are you seeing the problem when exporting

from the creation tool, or when importing into Flash, or when exporting

from Flash again for the web browser with some type of secondary

compression settings...?
