Here's a weird one. Anytime I open an existing Premiere Pro project on my removable hard drive, a folder named "Merlis" appears on the drive. Merlis was a project I worked on 6 months ago, and since then this has been occuring. I always delete the folder, but it keeps reappearing after I open another existing project. And remember, this is my removable drive bay in which I swap about 20 hard drives and it happens on all of them!
