Feedback is a very good initiative. I recommend to paste the link of our discussions on the feedback form.
My MacBook Pro (Apr 2011) was still Snow Leopard. My upgrade to Lion didn't give me troubles with trackpad. But my parents have purchased their MacBooks on october, with Lion installed. Up to now I didn`t manage to solve this issue (dragging only with 3 fingers). My mother has herself attached a mouse to make it easy.
We were thinking about installing everything from zero, with Snow Leopard and then upgrading to Lion, like I did in my own MacBook Pro, to get rid of this ridiculous 3 fingers dragging feature.
Now I will try this tip on their computers. Hope it works for every MacBook Pro.
Thank you. Please keep on sharing your good experiences and giving feedbacks to Apple, before they loose track again...
Regards,
Ciro.
