Using rexrainbow plugin I set up a small board in wich a mouse is supposed to move around.
It works in two step, first set up the board, and you can choose the color (frame) of the tiles, and once its done you can go to the second layout. The second layout will reproduce what you set up in the first, and once you click start add the board behaviour and the mouse.
It works
, but only if no frame were switched in the first layout.
I really don't understand why. I tried to do a simplified version to issolate the issue but everything worked fine in it. I uploaded the capx since the issue can probably not be found simply with my explanation.
