AutoCad 2011acting erratic - is it me or is there issues with this version?

[bdn2004]

When I go to STRETCH lines the selection set gets corrupted and things I don't want in the set get stretched too. Same with MOVE. I'm working on a large wiring diagram with lots of lines and text. It got to be too much on one drawing so I decided to make it into two...so I copied the entire drawing inside the first drawing and am working on the second drawing. I had no issue before this on the first drawing. ?

Do you have Parametric geometry constraints on? (see the Parametric tab, and lower left corner of your screen)

Thanks...that was it.
