I have a custom object that has a Visualforce page override for View, Edit, and New. When creating new standalone versions of that object, the visualforce page works fine.

However, if I am creating that object via a lookup on another object, the standard page shows up instead! It also shows up in a modal window instead of a new window.

I feel this modal window is the issue. How do I force the new object creation from a lookup use the visualforce page instead of the default page?
