The Lighting Controller

I have been working on creating 3D views so that we can show people what it is going to look like before we set it all up, and I am having problems with the orientation of objects. The y-axis rotates correctly, and the x-axis rotates correctly, but the z-axis does not always work correctly. When the object is not rotated in the y-axis, the z-axis rotation works correctly, but when the object is rotated in the y-axis, the object holds its z-axis (which makes the x and z axis the same). Has anyone else had any problems with this/has anyone found any solutions to the problem?

I am using the latest version of ShowXpress (6.333) on a Mac.

Yes, each axis depends of the others.
We will try to change this later.
The most important is you can adjust any wished position.
