Unsupported server version according WB.log : MySQL Community Server (GPL) version 5.6.15-log

Unsupported version isn't an issue - 2 of my other Saved servers are on the same version and work fine

I finally tracked down the problem, so hopefully might help someone:

The issue was in the server_instances.xml file found in:
%AppData%\Roaming\MySQL\Workbench\

There were duplicate entries for the server that did not work - I deleted the oldest entry for that server, saved and then reopened Workbench - All OK
