I'm having an issue with being able to drag and drop in premiere. What's happening is when I go to add a cross disolve to the end of the video that I'm working on it does not work. I get the little hand but below it there is a circle with a line through it. That is what's stopping me from finishing the project I'm working on. I don't know if it matters but I'm working off of a macbook pro and just installed premiere about a week ago. Any suggestions would be great!!
