Hello all,

Here's an interesting bug which threw me for some time yesterday. I was making a quick 
"not the 
same" check between two region objects, the first test being a comparison of areas 
(spherical in 
this case). The problem is it was stating that two polygons had very slightly 
different areas when I 
knew they were the "same" ie. node identical. The problem turned out to be that one 
region was 
composed of a clockwise polygon, the other counter-clockwise. MapInfo reports a very 
slightly 
different area for each which is clearly incorrect.
