Thanks. Saving the !p state did the trick. I have two related questions.

1.) Is there an easy way to erase the previous over-plotted lines without re-plotting the whole window?

2.) How would you suggest combining a single left-click to "click and plot something" and a left-click drag a rubber-band box to create a window to zoom in on the plot? I was thinking of putting the "click+plot" on a left button release event and have the box drawing on the motion, with a condition on release that if the new mouse coords are different than the old, then it's not a single click..so do the box thing and zoom.
