Stretch an existing Dimension ??

[eng426]

I just installed autocad 2012 and found that I cannot "stretch" or "move" an existing dimension on drawings. I dont use "grips" and was used to using the "stretch" command to adjust my placement. is there a setting I have on that prevents this or a way to move an existing dimension. (I have dimaso set ro "on")
thank you

Since I posted this question I found on this site "Dimtmove" which allows me now to move my dimensions although it does not allow me to move a "radius dimension". what do I do to move that?

thank you
