Draggin of Dimension Extention Lines

It seems that in the past couple of versions I have noticed that when I have to adjust

the endpoint of an dimension extention line it will move the entire dimension around in the ghost image.

almost like it is letting you select an alternate dimension point.  This particular

dimension was added in the drawing as apose to using insert model items.

For what ever reason that seems to make a difference.  Does anyone know how to

make it so you just linearly drag the extention and not the entire dimension?

The other thing is after I seemingly pick the new point it is very difficult to get out

of the process.  Esc doesn't work.  And after you pick the new point sometimes it doesn't

show the new point unless you select the green check box in the property manager.

And that seems to end the whole process.

Does anyone else find this annoying?
