There was a thread on this in comp.lang.javascript recently where
victory was announced but no code was posted:

On an HTML page how do you find the lower left corner coordinates of an element (image or button, say)
reliably across browsers and page styles? The method advocated in Ajax in Action (copy I have) doesn't seem to work in IE under some circumstances. To make the problem easier, let's assume we can set the global document style to be traditional or transitional or whatever.

Please provide code or a pointer to code please (a complete function that works on all browsers) -- don't just say that's easy and blather about what traversing the DOM -- if I want to read that kind of thing I'll go back to comp.lang.javascript. Please scold me if this is a repeat and point me to the solution -- I did try to find it.
