The 1 pixels fix doesn't fix the problem.  I tried expanding to 10  
pixels, but the ghosting still appears.  I do notice two things,  
however:
1) The ghost lines don't appear if I move the eraser very slowly.   
They only appear as I move the eraser faster.
2) The 10 pixel bound around the eraser is not cleared while I am  
holding the mouse button down and moving the eraser around (ghost  
lines continue to appear within the 10 pixel bound).  When I release  
the mouse button, and move the eraser across the ghosted lines, the  
lines lying underneath and around the eraser (within 10 pixels) are  
cleared.

I'm currently updating the XCode project, and will commit it later  
tonight or tomorrow.  If you still have access to the Mac Mini, you  
can then try building Tux Paint and check out the problem first hand.
