Details:

This only happens with the qt graphics

1) Run the attached program and enter 8 at the prompt.
  ( I don't like the fact tat the focus is left on the plot)

2) observe the red lines( they are correct)

3) select the Z+ zoom button.

4) now start a zoom in around the red lines near the center.

5) drag the mouse to make a box

6) the red lines have changed  This is the problem!!

7) finish the drag and let  it zoom

8) the red lines are wrong!!

9) now select the pan button and pan. now the red lines are ok
10) instead of the pan you can resize the window or anything the causes a
redraw and the red lines are then OK.
