iMac 27" and Autodesk Inventor GRAPHIC PROBLEM

Hi Everyone,

i use autodesk inventor with parallels 10 on yosemite with a virtual machine with windows 7 64bit. The problem is everytime that i make a right click in the graphic area it goes black like in the picture. Any idea?

 

I solve the problem setting up parallels with Directx 9...so the problem is directx 10
