Hey Bristol_Jonesey,
Now THAT makes sense, and probably has to do with permissions. Like said, Sonar writes a file to the root of the patterns folder of SD3. If it doesn't has permissions, it obviously generates an error. My weird problem is that it DOES have permissions to write, and of the two drag methods available, one works and one doesn't.
WHat I'd like to know: is there a difference in the two methods, does Sonar want to write files to a different location, when I drag from the browser immediately?
