Unfortunately Microsoft didn't fix all memory leaks with this new build.
There is another leak - if you have Bindings in an element that is inside Popup control - this control will leak. This is the case with RadComboBox, RadDatePicker and other controls that use Popup.
We are working on a workaround that I hope will resolve this leak but this will affect all our themes.
I'll write back once we are ready.
Sorry for the caused inconvenience.
