It appears the way they are coded makes them look like pop-up ads to internet explorer. So I've find if I right click and select open in new tab, or same window etc. it opens with no issues.

Same thing has been happening to me, but only with Chrome (Firefox is fine). When I try to click on the link, I can see a little "X" show up at the top of the browser indicating that the browser thinks it's a pop-up ad that needs to be blocked. Opening the link in a new window opens it faster than in a new tab, but both work.

Pop up? That makes sense and I am using Chrome. Had not considered right click, which actually does the same as what was the norm. Thanks
