You will notice than many, but not all, class computers now have the updated Adobe CC software!
Be careful, if you start a project using CS3 in one room and try to work on it in a different room. You will prompted to update the project file or it may tell you that the file can not be opened!!! You will need to manually open the CS3 software you need and then open you project using the 'File/Open' command.
If you use the New Adobe Software, you will NOT be able to open it with CS3!
