Thanks. Before I try what you suggest, I have one more question: Why does it matter how much space is on my C drive if it is not a part of the equation? (At least, it doesn't seem that it is to me - please correct me if I'm wrong) If Vue is on one drive with plenty of room (G) and I am choosing to render my completed file to another drive which has plenty of room (F), what diference does it make if a third, seemingly unrelated drive (C) is a little full?
