Hi Mike, I fear I'm lost in patches ;) Maybe you didn't want me to commit diagnostics.patch? I've tried Tests.patch with r4649 and 3 unit tests fail. The text in diagnosticmessages.patch should be adapted to our latest findings reg. the commit message ("diagnostic messages are now written to stderr unless using a logging configuration without a ConsoleHandler") Gerd ________________________________________ Von: mkgmap-dev <mkgmap-dev-bounces@lists.mkgmap.org.uk> im Auftrag von Mike Baggaley <mike@tvage.co.uk> Gesendet: Freitag, 9.

It adds synchronisation of the static variables in StyledConverter and fixes the unit test. It includes the not yet committed changes in codepage.patch, diagnostics.patch and Tests.patch. Cheers, Mike
