Thanks Ray, Updating the video driver did the trick. Thanks for pointing me in the right direction. Mike

I am having the same problem. I have a brand new laptop running Vista with 2G of RAM. After I render with OpenGL or Fast RenderWorks I use the 3d flyover tool. Then next time I click on anything, whether a tool or on the menu, my whole computer locks up. It locks up so bad that I cannot CTRL-ALT-DEL to bring up Task Manager to kill the program. I have to turn the power off on the computer. Thanks _________________________________ Windows Vist, VW 12.5.2 Toshiba Laptop A135 2G RAM
