You are probaby running Maya 6 . . . I know, I have run into a similar problem, textures are ok, but scale/rotate/move tools in side,top, and front views sometimes work, most of the time do not. Damned if I can figure it out . . . . just got a new book that explains the basic Maya window-building mechanisms in MEL, maybe after a little study of that i can figure out what the problem is . . .
May just need to upgrade a little too. . .
