Snap to grid is behaving undesirably

I am using SONAR Home Studio 6.

I have specified snapping of notes (actually CC: 75) to the value '405'. Notes were snapping fine at first, however, once I reached the next scale the snapping snaps at the very begin of it and I can't make it to '405'. Heres a screen shot incase you don't get what I mean: http://i50.tinypic.com/2vhwvvs.png
I am wanting the note to snap where the green dot is.

Does anyone know how I can stop this from happening, so that I can get the '405' distance?
