I've noticed an inconsistency, and I don't know if this is a bug.
Some of the links in resources in the Research Tab work (i.e. open another window when I click on them), while others don't work, until I manually open that particular resource, and then click on the link.
These two pictures show just one of numerous instances in which clicking on the link doesn't work. In the first image, when I clicked on the link in the red box, it didn't open. I had to manually open the BDAG, and then click on the link, and it finally worked.
