Ditto on both counts. I got the ad the first time I navigated from the Nexus home page, and I can't open Nexus pages in new tabs by any means other than right-clicking and selecting 'open in new tab. Neither Control-click (on Windows) nor Cmd-Shift-click (on Mac OSX) open a new tab here, but they work on other sites, and used to work here as well. I agree with Eiries - something's not right.
