Opps - slightly amended code..!!
> The following MB code uses an ever increasing circular buffer to look for
> 5
> nearest objects in BaseTable. BaseTable is a non-earth projection in
> metres.
>
>
> If the buffer centroid is (5,20) it works fine. If its (4.5,19.5) the
> search
> doesnt find any objects and gets stuck in a continuous loop. Any ideas
> why?!!
>
> Many thanks..
