Just to throw my two cents in, I did not have the problem described but I was absent from this site for a couple of months for technical reasons. Whenever I tried to post during that time, an ad would appear in the text box. This also happened on the WW2talk site. I have Bitdefender and usually use Firefox. I ran Bitdefender frequently, and for some reason the problem just upped and went went away about 2 weeks ago. I suppose Bitdefender finally caught and destroyed it. As you can probably tell I am a technical ignoramus.
