I am brand new to Toast. I can burn a DVD fine from iDVD. However, in Toast I get an "Couldn't complete the last command because of a Mac OS Error. Result Code = -39". I get this if I am trying to burn a DVD or saving as a disc image.
I am on a PowerMac G4 with 2GB RAM and over 190GB of HD space available. It should be the latest copy of Toast because I downloaded it last night.
