/****************************************************************************
The Popuppic Script
Designed for Netscape 4, IE 5, and Netscape 6.
Programmer: Andrew Drawneek
Requires: Is.js
26-Feb-2001, First version.
21-Apr-2005, Small fixes made to support browser version checks (screen),
added click to close (for both left & right clicks).
28-Apr-2005, Fixed bugs for IE: popupclick script now written into the
popup window, instead of being loaded from a src= line (which crashed IE).
Window width/height inner/outer differences are set to a default for IE
on Windows (because IE does not support inner/outer width properties).
This may have varying results on other platforms.
