I am unable to do a selection of part of a raster in Pixel Editor. When I draw a polygon or rectangle I cannot get the selection to close by double clicking. I have snapping on and tolerance set to 200 pixels which is well over the amount that I would need to snap. When I double click after setting the last vertex, the selection drawing continues no matter what I do. I have tried hitting enter and other keys but to no avail. Thanks for any help,
