OK, I don't have a "middle mouse button" I use a trackball which for me is WAY better for modeling than a regular mouse.
Issue is rotating views and such. I use the goofy block up in in left corner a lot.. which is fine but, it's so close to the edge for the window when rotating the pointer ends up off the window and the rotation goes in to freakout mode. Would like to be able to drag/relocate the block/cube to a diff place or at least move in a bit so it an be used a little easier.
