Works fine on windows but on my Mac no Joy , can't place anything can't save anything can't open older work from windows.
Comes up with 'Disk cannot be accessed' error message ?.
Definitely seems to me at least to be something to do with unhappiness with the Font cache,I have FontXplorer Pro which allows for easy clearing of the cache but it still seems only a temporary solution, I'm increasingly disappointed with the Mac version of this software, hastily released bug ridden versions were something that I thought Corel only did for us on Windows, seems not.
Did you installed already the update 1 for mac?

the performance should be much better after updating.
