Unfortunately, there's a bug in the encoder program, see the attached image. I've attached a modified version which fixes it. These are really great routines, I've created some videos using them and in some cases I've been able to get up to 150 screens to fit in 16K, of course it all depends on the complexity of the screens.

Regards;

Greg
