Hi, > Unfortunately there is something broken nowadays. > http://sourceforge.net/apps/mediawiki/jump-pilot/index.php?title=OpenJUMP_with_SpatialLite#Using_SpatiaLite_with_Spatialite_Reader_Plugin You report that a few weeks ago, but I could not reproduce the problem. Then, you told me you could not reproduce it either...
Is the problem there again ? Have you a step by step way to reproduce it ?
