I'm running into a few problems while trying to customize how WpfDiagram handles user input in my application.

I'd like to have left click act as a selection/movement tool, where you don't have to specifically select a shape before dragging it, and I'd like to be able to drag a selection rectangle when what I click on is not the movable area of a shape. In order to implement this, I've set ModificationStart to AutoHandles, and Behavior to Modify. This functions just as I want it, but there's one graphical bug; the selection rectangle doesn't appear as you left-click drag, until you've ctrl-left-click dragged once.

My other problem is with deleting items. Oddly, selecting a node and hitting delete doesn't delete the item; instead, I have to select it, then right-click anywhere, then hit delete. Is this a bug? Is there a way to change this? I'd like delete to just delete the selected item(s).

Thanks for any help you can offer,
