The FAQs starting at

    http://www.opengl.org/resources/faq/technical/selection.htm#sele0020

might help to set up and debug your picking code, furthermore there is a rather
lengthy tutorial at

    http://www.lighthouse3d.com/opengl/picking/

Do the PickSquare and PickDepth examples in Haskell work for you? They do for me,
but one never knows which bugs might be hidden... :-)
