IE has many leaks, but nulling a reference behaves exactly like in Firefox: The memory is not freed immediately, but it's freed after some other (unrelated) actions on the same page. You can test this yourself with the perftest.html page attached to my previous mail (use the create and free permanent object buttons). > There is no design flaw like this.
