Relationship Chart function - spurious errors

[Ron in France]

Have recently discovered problems with Relationship Chart. Not sure whether they started only since upgrading to 4.2.3 or only since my database increased above 10,000 individuals, both events occuring recently. Example of problem:
For two fifth cousins (having same 4xg grandfather) who also have other more indirect connections via more recent generations (eg brother of grandparent of one married to sister of grandparent of the other) the Relationship Chart shows this latter connection rather than the more direct one. 'Find next Path' shows variations on the latter path, until eventually 'No further path cold be found for these two individuals' is displayed. However, for other fifth cousins having the same 4xg grandfather in common, but having no other connections, the correct relationship chart is displayed.
Any ideas??
best regards
Ron

IIRC, there is a known bug in the relationship calculator, where it only finds one path of each length.
