Other IE Bugs...
I have found a memory leak in the implementation of JavaScript in IE 6.0 (it is in 5.5 and 5.0 also). I am not sure what is causing it but it seems to be related to an object storing a reference to an element that contains a reference back to the same object. Refreshing a page with the attached code in it will cause the amount of memory consumed by IE to increase and leaving the page does not recover the lost memory. I am using the loop at the end to exaggerate the problem so it is more obvious.
