General

This is a simple, cross-browser method for testing for pop-up blockers. Most scripts test the return value of window.open and conclude that there is a blocker installed if the returned value resolves to false in a boolean statement. However, these scripts fail with browsers such as Opera (as of v9) that return a window object but disable it. This script properly handles this, as well as a null or undefined return type.
