Symptom: I go to Chrome Experiments, click (e.g.) "Traveling Wavefronts" or "Solar System Explorer", click "Launch Experiment". A window opens. On top of the new window, a dialog box says "Your browser does not support WebGL".

Hardware: Dell Inspiron 1520, Core 2 Duo T7500 2.2Ghz. GeForce 8600M GT.

OS: legal Windows XP SP3 with all mandatory updates and many of the optional updates.

Driver: updated today, to the latest version on the Dell site for this hardware. The NVIDIA control panel says "ForceWare 174.31."

DirectX: 9c, all latest updates from the Microsoft site as of today.

Browser: Chrome. About box says I have the latest.

Thanks in advance for any help ...
