Problems with Monkey World 3D 4.2

Hi,



I have some problems with Monkey world 3D 4.2:


  1. I can't edit the terrain, I do clic in the "Edit Terrain" Button and I select the brush type, flatten height, radius and strength and the cursor with circle shape appear always out of terrain and I cant' move it.



    In the version 4.1 I can edit the terrain without problems.


  2. When I import the model in jme format. I can see the model but sometimes the model disappear.



    In the version 4.1 the model not appear, never.



    Somebody can help me???



    Thanks

    Regards.
