Thanks gebe :) I currently run Vue 4.2, but do not use OpenGL. I got in the habit of not using it from a previous computer where it never worked. I have an Nvidia GeForce 2MX 100/200 card on my XP Pro computer. Vue works great with Open GL turned off. But if I were to buy Vue Pro, I would want to make sure I had a video card that would run it effectively.
