The Second Life virtual environment company just added Snap Preview Anywhere to it's blog site, and there's supposed to be a way to disable the use of this feature-aggravation, but you can't put the cursor on the "Disable everywhere" option using the Opera browser because as soon as you move the cursor into the area that houses the "Disable everywhere" option the browser jumps to the linked page.
Anyone know how to disable the Snap Preview Anywhere under these circumstances?
