Another new version of the Chess Game Viewer has been published with improved code generation for the knight moves.
If you have included the JavaScipt in your own template then you are advised to replace it with this new version. If you use the external JavaScript, you'll use the new version automatically.

The new version solves some bugs and also has some performance improvements.
However I'll still advice to generate the coded moves by PalView, but I know that some of the users are not able to use PalView or consider this as too cumbersome.
