[BUG] Refresh rate to low after Display.close()

[tasty]

Whenever I run an lwjgl program the refresh rate is fine (it stays at 75.0 Hz) until Display.close() is called at which point the refresh rate is set to 60.0 Hz. The problem may have something to do with a newly install NVIDIA graphics card. The screen almost flickers just noticabley enough to be annoying at 60.0 Hz. Before I had this graphics card I think I used 60.0 Hz as it didn't flicker then. So it is possible that the problem has nothing to do with the graphics card or driver.
