ColorScale axis

In Igor 6.3.7.2, the axis on the ColorScale appeared to have a width of 0, and if you set the color scale frame thickness to 0 you have tick marks on the side of the ColorScale, but no visible axis line.  In Igor 8.0.3.3, the ColorScale axis seems to have a width of 1 point, and the axis is slightly offset from the ColorScale frame.  If you set the frame thickness to 0, there is still a visible axis on the color scale.  I used a Win10 machine for all these tests. 

Is there a way to adjust the thickness of the axis (or the axis position so that it overlaps with the ColorScale frame) in the latest version of Igor?
