jit.gl.texture isn't working on my max 6.05

hi i have max 6.05 and a mbp late 2011 (i7) with 10.7.2 running. my problem is, that jit.gl.texture doesn't work. in the help file no texture is shown, the grid shape object get the texture but didn't show it. if i open the sketch in my old max 5 everything works fine. is this an mac problem? thanks
