Weird iframe behavio

At the top of this page I’ve got the tabs installed and seem to be functioning properly.

Inside each tab I have an iframe embeded.

When the page first loads, the first tab’s iframe loads perfectly. However when I switch tabs, the second iframe loads super tiny, and then disappears. And then I cannot go back to the previous tab and iframe.

The other quirky thing is for some reason it is forcing links to open in new windows from within the iframe, whereas when the iframe is used outside of the tabs, it does not do that. This might be something being forced upon it by the embedded site though…

How would I go about fixing this?
