I could never stitch in this manner but I'm glad you found a way that works for you:D And, you made some other stitchers very happy with your tip:)
For me, it has to be paper. I cut my working copy into manageable pieces and attach them right to my qsnap. I need my chart to be close to my eyes and this way it's right in front of me. I could never stitch from my laptop{:3_57:} LOL;P
I think I do the paper-based version of this. I like to put my charts in a plastic pocket and mark the pocket with an overhead projector pen as I go along. That way I can see where I am up to and the chart isn't damaged so I can reuse it.
I'd get a headache using the computer for it.
