I am trying to use the QGIS (2.6.1) vector analysis tool "Points in Polygon". The points originally came from a KML file and the polygons I created new. I initially had a warning about different CRS but resolved that by saving the files as shape files with ESPG:4326 WGS84 CRS. Now the tool runs fine but the PNTCNT field in the resulting shapefile is all NULLs.
Am I missing something? What should I check for?
