I actually had found a way to fix this bug-- Using Ctrl+N to open a new window meant that, from the new window, I could select pages to edit, and the window for page editing would pop-up instead of replacing the current window I had open.
Suddenly, as of about 11:00 am EST, the new window that pops up remains completely blank. If I use my original primary window, the one I pressed Ctrl+N from in the beginning, attempting to open a page edit window results in the page editor replacing the current page (list of pages in the story) which means that once I finish editing, closing the window takes me off the site and offline.
From the secondary window, the new one that appears when I press Ctrl+N, I can't read published stories or edit pages. The tertiary window that pops up remains completely blank inside. Even if I return to the primary window, as long as the secondary window remains open, I can't read published stories. All popup windows stay blank.
I have no virus protection at all, and no firewall up.
Oh yeah, still Internet Explorer.
