Minor Tick Marks and Grid Lines

Hello,

This script shows two odd behaviours of tick marks
and grid lines:

(1)
The default minor tick marks do not line up with the
major tick marks.

(2)
Between 150W and 175W (and 150E and 175E) an extra grid line appears.

Is there any way to correct these behaviours ?

Thanks, Bruce
