Hello, i just bought a new PC, and when i install blender 2.64a, and put Cycles to render, when i try to change some material´s parameters while it is rendering, these pop ups windows don´t remains in the screen, it starts to blink (apears and dissapears constatly or when i move the mouse over them).
My pc specifications:

Edited: I just tried with blender 2.63a and Blender crashes when i change it to Cycles render engine.
