I have wondered for some time if it would be something that would not take forever to fix. I tend many times to not click on an ad, because it does not do an over when going to the site for the ad. The links in threads do overs so it is easy to get back. Ads do not.
Our setup here is one of protected internet access so we go through an internal portal page, then have to put in a password to get to the internet. If I close a site that I went to through an ad, I lose my internet connection, and have to go through the process again. If it had gone by an over, the cow would still be underneath. I hope I said this correctly.
