Clipping prob still, NEED help

[fugigoose]

Ok, makin a maze game. Have a character sprite that sits in the center of the stage. The map, which is a big sprite that hangs off the stages, moves to simulate motion (scrolling game). Problem. I've used the INTERSECT function combined with the matte ink in all my games, but matte only traces the outline of the entire sprite, not all the blank areas in between. Is there an easy way to make INTERSECT only return true if you hit the actual sprite (not the little white spaces). I really dont want to have to make each wall segment a diff sprite!
