When the above button is pressed, the Looking Glass should show a 3D image like below. To close this image, move your mouse over and click anywhere on the image. The image should appear 3D. If it appears with diagonal lines (as on the right), there is an error. Please retry the setup steps above to ensure it is properly configured. If that doesn't fix it, try troubleshooting. Once the setup is complete, go back to the [User Guide welcome page to begin working with the Looking Glass.
