... doubt I'm infected or anything ...

The pop-up behavior you describe sounds exactly like malware behavior. No one else appears to be experiencing this behavior. I strongly recommend that you run some anti-malware software on your system to scan for malware. If you're running on Windows I recommend the free version of Malwarebytes. Link to their site is below.

Good luck!

Mac OS X, El Capitan. And, this is the only site that this happens with--I do run nightly scans for malware. Seems the action stopped today, as clicking on the button does not pop up anything. Thanks, whomever shut it down.

It's not shut down. It's advertising code. It's not malware, it's a pop-up that we get paid for. As I stated, where do you want your refund sending for what you pay for this site?
Thanks for the great participation over the last 7 yrs also
