DrAzzy, that's sort of a drag about the 650 pixels high! My display is set to 1024 x 600 and I don't believe I can set it any higher. There is a 1.6.11 version now that I might try again, otherwise I'll go back to an earlier version.
pert, I don't know if I'm in portable mode or not - just downloaded the 1.6.10 from the Arduino website and don't recall specifying any options during the download. I'll look around and see what I can find.
