I can't seem to get houdini to run properly on my windows 7. The apprentice version downloads fine but the modeling space just shows whatever is behind the houdini page. For instance if I open Houdini off my desktop, I can see all my icons in the modeling space. This would typically suggest a graphics card problem except that my graphics card is sufficient to run Houdini. Anyone have any suggestions. I'm falling way behind in my class. Thanks
