Over the last couple months I've been trying to learn more about photoshop. I've used paint shop pro for years but there were things in photoshop I wanted to use so I splurged. Anyhow, when I render in poser I save as a psd file. Paint shop pro and Photoshop can open this file. But if I use photoshop to do postwork first and resave it, paint shop pro can't open it even though it will give a preview thumb for it. I get a not a valid psd file from paint shop pro. This is very frustrating as I am more comfortable in PSP and still do the things I don't know how to do with PSP. Anyone know what's going on here? btw... this is Photoshop 6.0.1.
