Can't open any tabs
Gets stuck on "Loading Selected Tab - Please Wait"
I'm using the 2.2.1 unstable version. All of a sudden whenever I click on any tab from an article, it just hangs at the "Loading Selected Tab - Please Wait" with the progress.gif above it. It worked fine yesterday, and I haven't changed anything at all. I've tested on multiple articles and multiple browsers. I can return to the article tab just fine, but all other tabs hang.
