However, I was stuck with it in the top one-third of my sidebar because an Adsense promo was blocking access to the lower parts of the blog layout interface, in both Firefox and Safari (below). No scrolling available to get past it, even after refreshing page views.
FirefoxI tried following the link to the Google Adsense interface, not activating anything, and navigating back to the blog layout interface, to no avail.
Finally, after closing Firefox, and firing up a new window, starting this post, and taking another look at the Blogger layout in another tab; the layout loaded completely, and showed the remainder of sidebar elements. However, in Safari, even after quitting and relaunching the browser, reloading and refreshing the page; the AdSense promo is still stuck there about 5.5 gadgets down a sidebar of 17, hiding 11.5 of them.
