That could indeed be the difference that makes things break on your end. There has been some ground work for doing automatic testing on Windows to detect these kinds of problems... it will probably be fixed soon. > > I noticed one thing that in your 1.3M02 built doesn't include library > neo4j-index-XXX.jar.
