I have Pantovision and trifocals! I did have some difficulty with focus early on. I think I like it better when I pull the panto out just a bit. I quilt 15 mins or so at a whack..then increase time as my eyes get accustom. I have not done enough with it to find my preference. I think one time I had the panto moving...and the next time I had the cursor moving! Looks like I will need to quilt more to figure it all out. Have you checked out the yahoo group for PV? I will look it up and post in a few....
