An Icky Solver

This killer sudoku solver will supposedly solve your samunamupure, but I can't get it to work. (Has anybody had any success with this thing?) It definitely gets a "D" on the usability scale: You click on the little blue lines on the left to select each cage, and then assign the cage total on the right hand side. (As the headline says, it's icky!) But if you're stuck, this is what desperation will do to you...
