Thanks for the input, I need to see if I can repeat that.

:-)

It's not the gui that takes 100% cpu, the game generates new boards in
the background for a while.
Generating boards (at least in my implementation) takes some cpu.
You know in erlang you can spawn processes to do work while waiting
for user input. :-)
But if you wait some time it will have generated 5 boards and it will
slow down.
