This is where things are going wrong: there should not be a second
window. Instead, the second prompt should appear in the same window.
I just tested this on Mozilla on Mac ... where everything worked fine.
Which browser was this? May I ask you to please file a bug at
http://bugs.lon-capa.org/, specifying the exact browser type, version,
and platform?

Yep, the second window is the problem ...

... try another browser, or enter coordinates by hand.
A correct coordinate pair for a rectangular shape looks like
(88,48)-(119,69)
which is (x_upper_left,y_upper_left)-(x_lower_right,y_lower_right) in
pixels - one could get the coordinates from Photoshop.
