Matsolund, if you are using 'Open' from the Finder 'File' menu and you are still having problems opening some of your Bryce files, do as Dan recommends and fix permissions on your Mac. I would recommend repairing permissions and cleaning up the system caches. Use a tool like Onyx (get it here: http://www.titanium.free.fr/pgs/english.html) it keeps my iMac G5 happy... Garry
