IDL Contouring Error? [message #75867]

In contouring certain variables (e.g.' temperature) across North
America, IDL is doing something very interesting. Along the US/Canada
border it seems to encounter an error that causes it to draw contour
lines where they should not be (e.g., between two values that I have
specified to be within the same contour level interval. For example, I
specify 0, 0.1, 0.2, etc... and it draws a line between locations with
values of 0.13 and 0.14.

MAP_SET is called, but otherwise I can find no reasoning for the
location of this error at the 48th parallel.

Anyone ever seen something like this?
