Thanks for your reply and yes, I got the update. For a variety of reasons I really hadn't used Waveburner until recently so I don't know if this was a problem before then or not. Also, I am using s MacG5 Dual 2.7 AMD chip so that may be part of the issue although I would have to leave that up to the experts to find out. Since I haven't seen any other posts on this topic I might think that that had something to do with it.
