problem with illustrator cs6 alignment
I have a problem with my illustrator cs6 option.
When i want to create a new shape, or text or tring to duplicate with shift to maintain the shape straight. That does'nt work. The shape is automatically rotated. I tried to reset my artwork preference. I tried to change some properties in the perspective grid. Nothing work. 
I can doing nothing straight. How could I solved this problem ?
