A minor release of Density (5.0.3, 21 April 2014) fixes a bug that could cause some points to be dropped from the computation mesh. When 'Trap buffer' is ticked in Options | Computation (the default in 5.0), the mesh used for 2-D integration is clipped to exclude points greater than the 'buffer' radius from any trap. A coding error caused the last trap to be ignored, so the mesh could be smaller than intended. This is unlikely to have more than a trivial effect on estimates unless the buffer radius was too small in the first place. Thanks to Mike Hooker for pointing out the problem.
