colour of a list of polygons
it seems to me that this is a bug:
open the file and move the slider. when its value gets bigger than the value on the opening, the colour of the following elements of the list appears changed.
maybe it has something to do with it that there are 3 coloured areas (2 lists + 1 integral) one onto the other.
(well... after checking a bit, the behaviour persists even one by one).
