@dicinson: Amazing! It worked, thanks! This should be posted on a forum somewhere. I found the exact folder and it was almost a year old but never noticed these problems until after Opera updated a couple days ago and a whole-page pop-up relentlessly would flash on top of my page every few seconds then disappear! It's incredible to me that Opera would succumb to this behavior and take the risk of losing a huge part of their client base. I seriously have a bad taste in my mouth for Opera now and am considering pulling the trigger. Thanks again for the hack.
