I had this same problem today and found a solution for it. In my case, the problem occurred because I was using a network disk for storing my project. When run from this network disk, this problem occurred. I moved the project to my local hard drive and it was gone. I am guessing this has something to do with security, as Windows considers the network drive less secure than my hard disk.
