The "opener" property of the popup window is a reference to, well, the
opener. ;^) It links the window which opened the popup.

So you might, to populate a form field in the main window, say (from memory
so I may be a bit off):

window.opener.forms.MainForm.SelectedClass.value = "Whatever they pick";

If you have a variable called "CurrentClass" in the main window you can
populate it from the popup like:

window.opener.CurrentClass = "whuddeva";

"opener" is a top-level element: if your popup or your main caller uses
frames then it might get more complicated (you'd have to chain the reference
out further)... but it's still definitely doable.

Good luck!
