Google Chrome Version 42.0.2311.135. When I middle click to open this link in a new tab, or use "open in new tab" or "open in new window", no tab or window seems to open. If I press the middle mouse on the link rapidly the tabs to the left jump as though a new tab is being created and then immediately closed. The link works if I left-click it. Is anyone else experiencing this? This seems to be the only link doing this. Is anyone else experiencing this? Oh, looks like the popup blocker is blocking it?
