It's always been my practice to make sure that these sorts of objects are created in a specific order. For example, say I want to have a TreeView load pictures from a ImageList which gets them from a PicClip control. I create the PicClip first, the ImageList second, and the TreeView last. This was when the parent form is instantiated, the PicClip initialize first, then the ImageList, etc. Saves lots of headaches.
