I tried using one of the standalone overlay demo webpages as an external link launched from inside a tab pane.

The overlay page functions perfectly on its own. But when it it inside a tab pane, the overlay misfunctions -- while the overlay does come up, the linked page does not appear, and there is an additonal white overlay laid over the expected overlay.

(Hard to explain, but here's what it looks like:)

Click on the middle tab, then try clicking the Show External Page in Overlay button, and you'll see what I mean.

Thanks for any help!
