I think I know what Darkmoon is talking about. When you read the forum posts, there will be highlighted blue words, such as the post made by Lilly Ivy above, where it says get Firefox. Some people, like myself, read posts by using our mouse icons to make sure we read every word. When you hit blue words in a post, a little box with an ad pops up. Sometimes accidentally moving your cursor icon over one of the blue highlighted words causes the ad to pop up as well. That box lingers for quite awhile and hinders reading of the entire post, especially if it is a word in the middle of the post box. Until that little ad box finally disappears, you can't read what the ad is blocking. I use IE and this happens, but I also use Firefox (which is what I am using primarily)and it happens either way. Also, the weight loss ads that are often seen on this forum are quite, uhm, well, for lack of words, insulting? I understand weight loss is health related, but the particular ads shown are those ones where it says something like "How I lost 50 lbs in two weeks" and I have accidentally clicked on one, and when I tried closing it, I got a little notice that looked like a Windows Error box and it said something on the lines of "I know you are skeptical, but look at my results. Are you sure you want to turn down this fantastic offer" and I actually had to close down the entire browser to be able to close down that ad offer. I do have antivirus and malware/spyware removers and I am sure the ad was not dangerous, but it was tagged as spyware. I think ehealthforum needs to seriously look at its sponsors and make sure they are legit. After all, this is a health forum, not youtube or something like it.
