Wave simulation gregsn - 2nd monitor question

… another (perhaps stupid ?) question to gregsns wave simulation:

Why is the Renderer not working on a secondary monitor ?
Even if I move the first renderer also to this Monitor it is still not working.
Does it have to do with the Device-setting in the Renderer ? Is there a documentation about this settings somewhere on the Wiki - i did not find it ?
Does it have top to with settings of the shaders ?

its a bug. i will have a look at.
