Thanks! The humorous re-sizing really makes the point. I very much appreciate your help Philip. Michael On Feb 11, 2010, at 8:46 PM, Philip Ryan wrote:

This gives me the idea. May I ask: * regardless of what place option I use: ne, se, nw, sw, etc., they all put the text box in the lower left corner.
