Hey Frank – you can read the thread above for more information about this issue. I went into some further detail about the problem here:

The best path forward here is to make sure you’re using the latest drivers for your graphics card. Let us know if we can provide additional help here – we’ll do what we can, but unfortunately this is a graphics driver issue, meaning it’s not something we can fix directly.
