I don't think that is the problem Scott. I had XP with NTFS partition without ProPack and could save .cr2 and .obj files fine. Hogwarden -- Does this affect just one tester, or multiple testers? If it's just one, then maybe it is something on his/her machine. I have not run into this problem on my PC with any file manager. I would be willing to test it on mine if you need someone else who has XP with a NTFS partition. Actually, I have two PCs that I can try it on to see if it occurs. One is an Athlon system, and the other is a Pentium III. Send me an email at jmcleaver@attbi.com if you need any assistance with this. I do plan on buying it when you release it; I am not expecting anything. I just want to help you to get it released so I can buy it!
