About a week ago I installed Maya on my (not very new) Laptop computer (Acer Travelmate with XP Professional and ATI Mobility Radeon HD 2400 XP). At first everything seemed to work fine, but recently I have noticed some options are missing in the Attribute editor when trying to edit material nodes (like Special Effects, Matte Opacity, Raytrace Options, etc). The tabs are there, but when I click on them they don't show the related attributes.
Those same attributes are present in the Channel Box though and altering them shows up fine after rendering.
Does anyone have an idea what the cause of this problem might be? I have never run into this before when using Maya on my other (desktop) computer. Help would be greatly appreciated.
