Hi Mike

Thanks for the response but that doesn't seem to be it. I'm definately clicking on the arrow.

Just to clarify (hard without actual video of the problem);

What I see in the tut is a number of verts are selected. The move manipulator appears at the centre of the selection. As an example, the x-axis of the manipulator is clicked and then another vert is clicked on with the middle-mouse and the 'v' key pressed. All verts align in the x-axis with the target vert.

What I get is that the manipulator aligns in the x-axis with the target vert and the selection of verts remains at their relative x-distance from the manipulator.

Thanks again

MrR
