After your last reply, I went through and (as far as I know) ensured I was removing all event listeners and setting the object to null. I spent quite a lot of time trying to make sure there were no more pointers to the object but it still made no difference. Thats when I implemented the method you suggested of re-using the objects.
Interestingly, it always used to crash around the 28mb mark but now it goes beyond that and runs fine. It did seem to be the sheer number of objects rather than the amount of memory being used.
