Can you try the testSHLXXXX_shaderprog examples just to be sure nothing crept into the compat implementation. I had a attribute aliasing problem on OSX recently. Oh and could you try the testSHLGeomteryShader example, that was the only one working on OSX interestingly. Let me get back to office and give the 64bit Win7 version a try. kind regards gerrit ------------------------------------------------------------------------------ Enable your software for Intel(R) Active Management Technology to meet the growing manageability and security demands of your customers.
