Memory leaks - Ideas?

We are planning to use the grid in an AJAX application and experience memory leaks when using the grid.

Is there a way to explicitly release the memory if the grid is not used any more? Currently, we remove the DOM objects and set the grid javascript object = null.

Thanks in advance!

Just to clarify: we are using Version 2.0 RC 1.

I think the leaks were supposed to be fixed in the final release, I have not yet tested for them. Alex was fully aware of them.
