I agree with you 100% on that mikedaddysmooth don't get me wrong Bryce is the easiest 3d program to learn IMHO and I love it when it works but you do get <censored) when it decides to throw a tantrum and lose a lot of the work you lose. Perticulary if you have worked on it for a long long time.

The trouble is it is a computer program and at the end of the day all computer programs have their flaws and glitchs.

ddaydreams there is one thing you might need to know once the bryce 6.3 file has been saved in Bryce 7. 1 Pro it will no longer work in Bryce 6.3

the invalid address issue in Mac OSX Snowleopard is a daz3d.com.apple.plist problem. Some people on Daz forums say to delete the .plist but I suggest you only do that if you know it won't keep causing these problems because now I can't even find the files the computer keeps babbling about my theory it is that certain bryce file gone corrupted. Another Thing if you ever decide to buy a new mac to put Bryce on wait and see if Mac OSX Mountain Lion has good reviews and is Bryce Compatible Because you can't revert back to snowleopard with a new mac OSX lion because the components rely on that specific operating system.

Thanks
