I did a search and came up with no results, but I can't believe that I am the only person to have this issue. I have a Mac Mini that I purchased new early 2010. I just notice this past weekend that my copy and paste as well as drag and drop stopped working. I have been ripping a bunch of DVD's using handbrake, updating meta tags in Meta X, and then importing them to iTunes. I first noticed the drag and drop when I tried to move files from a ripped folder to an imported folder after getting them successfully into iTunes. The copy and paste issue was when I was trying to populate some description fields in Meta X with information I copied from IMDB or Amazon to give a brief description of the movie. In both cases, nothing happened. I'm not sure where to go with this. I have not called Apple Support and the nearest Apple Store is over an hour away. Any thoughts? BTW, I am running the current OS and all software is up to date with the current version.
