Hi all, after installing Maya on my new laptop computer I got the same problem as Kurokawa. I installed maya several times (versions 6 PLE, 6.0 and 7.0) on internal and external HDDs. The screenshot shows the problem for the Convert NURBS to Polygons options (or lack of options...). However, in the Create NURBS menu the submenus appear correctly with Cylinder, Cone and Plane but not with the other primitives. :headbang: The most frustrating fact is that Maya from the same installation disk runs (slowly but otherwise) without problems on my 4-year old athlon 1.4 GHz w/ 64 MB graphics. PLEAZ HELPP!? Anyone?? ------------------------------------- DELL Precision M70 1.73 GHz Pentium M Windows XP Professional SP2 1920 x 1280 TFT & 1600 x 1280 CRT (external), extendend desktop 1 GB RAM NVIDIA Quadro FX Go 1400 (256 MB)
