Shader Development Studio Problem

Hello,
Recently I decided to try out Mali Developer Tools, which look very promising.

Unfortunately I have a problem with Shader Development Studio.
When trying to make SimpleTest Project (from the User Guide) while rendering the shader effect
the Shader Preview shows a triangle instead of a square shown in the Guide.
In general, it is not surprising, since the option VERTICES in Shader Attributes View has by default  three
vertices:
-1.0 -1.0,0.0,1.0,
1.0 -1.0,0.0,1.0,
1.0,1.0,0.0,1.0,

The problem however is that there is no possibility to add additional vertices
(when choosing the option USER_DEFINED). You can only change the three given.
Changing the geometry in Shader Control View do not bring any effect, always showing three vertices.
Even when using a Shader Examples from Mali GPU Shader Library shaders are applied to that triangle.
The shaders themselves are working (changing color, texturing, etc).

Plugin has been tested on the following configurations:
Eclipse 3.6.2
  • GeForce 9600M GT Windows 7 64bit
  • GeForce GTS 250 Windows 7 32bit

All necessary OpenGL extensions are present, Emulator and Offline Shader Compiler are installed and work.

    Looks like I have the exact same problem on WinXP.
    Eclipse is v3.7.0.
    GPU: GeForce 8300GS
    The Mali OpenGL ES 2.0 Emulator works fine when used intependently of the Shader Dev Studio.

    I've tried both creating my own SimpleTest as per the PDF docs and importing ShaderExamples from the Shader Library but all I can render is single triangle.
    Changing the Geometry from the Shader Control view does not help.

    It's just using the hardcoded values from the Shader Attributes view. So if I edit them I can modify the render but I can't get it to use the Geometry specified by the Shader Control.

    Am I simply missing something or do you have a bug with the latest Eclipse release?
