Il tried again, and il works ... for circle and rectangle. But for the star, it does the same thing, with or without the Shift pressed. Il suppose il is ok ?
Thank you for hour help Brynn.

Hello , I want to draw a shape (eg, a circle or rectangle ) from the start. I press the Shift key , but it does not. I run Windows 7 and my laptop is Asus.
English is not my native language, thank you very much to answer me with everyday words .
