OT: Javascript to close any prev open windows

[RGould8 at aol.com]

I realize this doesn't pertain to Revolution, but I don't presently belong to 
a Javascript listserve, and the folks on this list are probably smarter than 
the folks on a javascript listserve anyway ;)   This actually is for a project 
using Rev, but this occurs after Rev launches IE and quits itself.


-----------
Does anyone know if a means in Javascript to write an "onload" handler that 
detects any previously opened windows in Internet Explorer and automatically 
closes them when the present html page opens?

something like:

body onload="window.close()"

except that instead of closing the present html page's window, it'll close 
any previously opened windows.   Unfortunately, we don't know the "name" of the 
previously opened windows.

Any advice is greatly appreciated.
