1.Select the application and choose File > Get Info. 2.Select the "Open in the Classic environment" checkbox and close the Info window. 3. run application. This should run any older applications in Tiger OS in the Classic enviroment for applications that require OS 9 etc. The other thing is to contact the application maker for mac converter and as them, I didn't see any update since '03. However an email may help solve the problem. email question to : MartinC@soft-rabbit.com I have played in OS X, haven't had much use or time on Tiger OS yet so I really am not much more help. shrug
