i am running maya 8.5 on a intel macbook pro. my problem is that when i create any kind of primative, there is no creation history. so if i create a poly plane i am unable to add any divisions in the channel box. in the channel box under shapes it says pPlaneShape1 and there is nothing under it. this is a recent problem, i have been able to do this before on my same setup so i am wondering if there is a setting i accidentally checked.
