>Pam, try just looking straight ahead at your monitor, both eyes open. stick your forefinger in your line of vision. Alternately close one eye, open it then close the other, no need to really worry about focus. When you close your dominant eye, your finger will appear to jump sideways because the non dominant eye is taking over. When you close your non dominate eye, your finger does not appear to move because your dominant eye already has control. If you focus on the monitor, the results will be more exaggerated than if you focus on your finger, or don't focus at all, but should still be the same. The closer you hold your finger to your nose, the more exaggerated the results will be. If you don't see this result, then I'm out of suggestions.
