voronoi bug?

Hi,

When I create a voronoi diagram through c# I get the same error quite often. When I convert the cells (cell2) to polylines I get ONE polyline less than number of cells. And when I look through the list of cells I can see that one cell has 0 vertices. Is this something anyone else is getting or just me?

Thankful for any help!

Regards,

Johanna
