Zooming bugged when single step is plotted

When simulating multiple steps, but only plotting one step, the zooming does not work.

Steps to reproduce:

  1. Draw circuit as shown below:
    image
  2. Run simulation, and plot net “Out”
  3. Hit F6, and plot only step No. 2.
  4. Quit the Simulation Step Tool window
  5. Draw a rectangle to zoom in

Now you see the vertical axis scales to 0dB…100dB, instead of the zoomed area.
