Hmmmm..... According to GPU Caps Viewer my laptop only supports OpenGL 2.1, and 2.6.1210 does not work at all with OpenGL enabled. I'm running Windows 7. See the enclosed for an example of what I'm seeing - some charts won't render even if they appear to load, and doing much scrolling or zooming causes crashes. Are older revs of OpenGL supported? FYI, it appears to work fine with OpenGL disabled.
