Setting "MaskLand" Changes Gridline Settings

Hello,

I am having a problem keeping the (dashed) settings
for my grid lines when making a map. If I use

    res_at_mpGridMaskMode = "MaskNone"

the results are what I want. If I use

    res_at_mpGridMaskMode = "MaskLand"

the grid line settings revert to the NCL defaults (?).

I have attached a script to demonstrate this. By
switching the above lines (at line numbers 49 and 50)
you can see the results.

I am running NCL 4.3.0 on Cygwin (Bash on Windoze).
I get the same result with NCL 4.2.0.a034 on AIX.

Thanks, Bruce
