Thanks for that, i will certainly try that later. I think i will hang on a while longer though before upgrading as according to the apple support community forum people are having other problems. I have the same concerns about if Bryce 7 and Daz studio 4 will work. My reasons for thinking about upgrading to Lion were to take advantage of "gesture movements" and the cloud so i can synch with other devices easier. Beginning to think is it worth it just yet.
