Yes, copying the .png from another program (for instance: IrfanView, or
a browser) into PGS gives this black alpha-channel.

However if you export or save as such a picture as .png, and placing
(loading) that .png into PGS gives transparant Alpha-channel.
In a browser: right click at the .png link and do a Save link as... and
save it anywhere on your harddisk. Place this .png into PGS.
Both methods work, at least in PGS 5.0.3.4 Windows.

(Tim is working mostly with the Linux-version of latest PGS-version)

ps saving :-(

Yep, I'm using PgS on linux. For this purpose my windows install doesn't help
because, as testing it just now shows, the problem is when printing. Or...

New Document
Import png with alpha transparency, it displays perfectly
Print document (to a postscript printer), the alpha channel is printed black

My windows install is currently unable to print anything (my unreasonable
requirement that Win2k must print via IPP -- mostly doesn't work and right
now completely doesn't work)
