Ask Fury, he's the one that set it up. Most likely he'll not know though.
I saw that menu and another site on the same day that fury set it up here, and if the point was anywhere in the space beside, ANYWHERE across the browser window, it would pop out, even if it was inches away, which kinda sucked. That was in Netscape.
Does it only do it in Opera? I used to use Opera, but I just kept running into too many sites with flash and shockwave, so I gave it up over and over. I would love to be able to se it on a regular basis though.
