I have a Dell Lattitude E5400 running Windows 7 x64 and decided to try the IE9 beta that has just been released. Unfortuneatly, the browser crashed on every page load. After some investigation I found it was caused by my graphics driver. The E5400 uses the Intel GMA graphics driver from the Express 4 chipset.
Problem driver version was 22.214.171.1241.
Working driver version is 126.96.36.1992.
You can get the new driver here:
