I have been using for 2 months now and I hate it. I have had a number of problems calibrating one of my proofers with it. I cant stand the User interface and how confusing it is. You dont know what is printing next, you dont know what percentage of your proof is left to print. To me the menus make NO sense at all. For example If I send a page over and then decide to delete it from the print queue, that doesnt do anything. The file still resides in another "queue" ready to print. Im really hoping to hear others experience with this.
