Pop ups when trying to click inside reply to posts

This has happend before. I compose a message to reply to a post, and if I click to try to move the cursor, I get taken to a different page that opens in a new window. Today, it has been an ad for Bridgestone tires. It happened in this post if that makes a difference at all,

It is incredible annoying as I have to backspace to the previous page to get away from the ad. (cant click on or anything while this happens) loosing whatever I have just written. (cant click to copy and paste to save anything, just get taken back to the ad)
Does this happen to anyone else?

I haven't seen the problem before. It sounds like you might have a sticky mouse. It isn't moving and you're actually clicking on the ad.

What browser do you use?

Click to expand...

I am using Opera. And nope, not clicking on ads, the cursor never moves out of the text while I am typing. It only happened the once today, but it has happened before, again with Opera.
