I am not familiar with the shaders product but pixel shading requires activeX 8 or better and OpenGL. Maybe you installed Poser 6 with SreeD and when you installed shaders it flipped the switch to OpenGL. Right Click on any part of your desktop that does not have an Icon. A window will pop up. pull down to the bottom where it says properties and left click. Your display properties window will pop up. The last tab on the right is the settings tab. Click on that and you will see a monitor image and a slider for screen resolution. between the two should be the word display and your monitor and video card type. Find out if you have an Nvidia or ATI graphics card then get the latest driver from their website. Don't try to update with windows I tried to update my video driver in the hardware manager and it told me I had the latest driver as of 2003 but Nvidia had a newer one on their website.
