CC; I've never had anything like that on here, other than a ticked off member who was able to infect the site. Thought at first you might have been the first hit with something new on the forum - but then realized you said that sometimes it is worse than others. So this has been happening to you for awhile. Others will chime in if it has been happening to them. Otherwise it may somehow be related to your set-up. In either case - contacting the forum administrator may help.
