Yes it does (see my message of 13:33 GMT 6Feb).
Ed has now explained why PSP can't read his compressed
48-bit ones as opposed to Adobe's allegedly compressed but
larger files.

So JASC could alter their import routine, but PSP still
wouldn't be able to write a 48-bit image, so there's not a
lot of point in it. I have quite enough trouble with 24-bit
myself, so I'm happy with PSP7.
