Frame buffer exposure correction dissapeared?

[upshot]

3ds Max Design 2009 - VRAY 1.50 SP2

My exposure control slider in the color corrections window has disappeared on a scene! I tried closing and reopening MAX but it's still gone? Any ideas?

You could try to change the renderer to scanline and back to V-Ray and see if it comes back. Before that you can save your render settings as a render preset do that you can restore them afterwards.

Same problem here on V1.5 SP4 on Win7 64bit
