Today I have a weird issue with this Microsoft ad:

As soon as this ad was loaded (which takes its time) I can not click on any other links on this tab. Before the ad was loaded everything is as expected. Links on other tabs are not affected.

My further investigation revealed that it is left mouse clicks only that are affected. Opening links with the right click context menu and the link from 1 question with new activity work fine.

This is the source code on my browser:

Paradoxically the issue occured on I.E. 11 on Windows 7 (no ad blocker installed) that I have to use here. I don't mind SE to make some earnings from ads but they probably should not behave in such a way.

• I've identified the campaign in question, digging to try to repro and QA if possible. – stevvve May 31 '17 at 15:39
• @stevvve: thanks. Now at home on Ubuntu Chromium the ad is a different one (no issues there). – Takkat May 31 '17 at 18:12
• Yeah right now we're having a difficult time even seeing that specific ad (even in our ad server), let alone reproducing the issue. – stevvve May 31 '17 at 18:13
• Added a link and source to the MS ad as of today - same issues than before. – Takkat Jun 1 '17 at 6:25
