Still works for me, although a little bit differently.
If you do not have the side bar open, double-clicking the patch will open the object explorer. Here is the different part, you need to double click something in the object explorer if you want it to appear where you double clicked in the patch. To make it behave more like Max5, turn on "Hide Explorer After Creating Object".
If you have the side bar open, double clicking will focus on the object explorer tab in the sidebar. Again if you double click one of the objects it will appear where you previously double clicked in the patch.
