The way to delete the polygon ground pane pour is to open the board,
such that you have the blue line around the edge. Type in the command:

polygon;

The";" character reverses EAGLE commands.

Now, click one side of the blue rectangle that indicates the extent of
the polygon, and that side will disappear, becoming a diagonal to the
corners. Click on the diagonal, and the polygon is gone forever.

By the way, for those who haven't figured it out, when you type in the
command polygon gnd to start a polygon of the gnd signal on the
current layer, windows open up with Miter, Width, Isolate, Spacing and
Rank. The important one is Isolate. That allows you to specify
directly how much isolation from the poloygon pour the pads get.
