As often in this case the map is damaged, with the warning : ""Coor files of vector map is larger than it should be (XXXX bytes excess)"" After rebuilding the map, the only way to restore it is to purge the zero-length segment, then everything runs fine again for your map. wxdigit should prevent removing a vertex to a line if it's made of less than 3 vertices, or implicitly delete the single remaining vertex." defect new normal 7.2.4 wxGUI svn-trunk digitizer, remove vertex,zero-length Unspecified Linux
