I am running Photoshop CS5 Extended on a Mac OSX 10.7.3. I can not copy or align any files in Photoshop. This happens no matter what I do or how the file was created. I have tried everything and nothing seems to resolve the issues. It is not a locked layer, I have checked all my preferences and I am using all the default settings. I am at my witts end!
Basically what I have been doing is to use Fireworks but I now have to use Photoshop for a certain project.
Any help or advice would be much appreicated.
