Again, just a guess, but I don't think anything has actually changed. It's just the mac trying to interpret the extension/data As an example I have just started using the 3D app, Poser. When I save a file it gets the extension .pmd. This is seen by my Mac as a "Microsoft Excel Binary Document" and given an icon corresponding to what looks like a Classic version of Excel - not the newer icon set at all. It was made by Poser, but my mac doesn't believe me. If you get a chance look again at this OOPListDocumentType and see if the icon is an orange colour (I think) - OOP tends to do things in orange HTH -- M
