remove selectability of referenceobjects

Imported a highpoly Object as Reference. But everytime Im trying to draw on top of it, i get "overflooded" with Snap points. But if I turn off ObjectSnap, then the Curves Im drawing are disappearing beneath the reference objects surface. Kind of Hard to work in Moi when you dont have a standard move rotate and scale tool like in other 3d applications.

Is there a way to remove the selectability of referenceobjects ?
