In my application I use glGet w/ GL\_MAX\_TEXTURE\_IMAGE\_UNITS to query the number of available texture stages and then use that value to restrict the stages textures can be bound to.&nbsp; Using the OpenGL ES 2.0 PC emulator (2.07.27.0297), this returns 32 on my system, which has a GeForce 8800 Ultra.&nbsp; However, when I call glActiveTexture, I get the following error  
  
In glActiveTexture error: 500 (GL\_INVALID\_ENUM) : texture number is out of range (min: GL\_TEXTURE0), max: GL\_TEXTURE0 + 7, given: GL\_TEXTURE0 + 8  
  
Is there an inconsistency in the value returned for GL\_MAX\_TEXTURE\_IMAGE\_UNITS and the error checking taking place in glActiveTexture?
