Every time I go to click a link, or open a new Safari window, nothing seems to happen. No window, links don't seem to work, though they change color as if activated. Did some searching, found that the windows are opening just fine, but opening on a duplicate screen somewhere where I can't see them. Figured a simple restart would fix this, and it did--for about 3 windows. Now it's right back to the same thing. What's the fix? All software/updates are installed/current.
