For a free slider, this works a treat. Actually, it would still be great if it were a paid version. I've had no problems using it in 3.1, even the suggested problems with captions didn't happen. Highly recommend.
Just want to say how grateful I am to the support staff for getting this extension working for me. I found it fairly tricky to install, but that was more a problem with Facebook and my own limited experience in the Facebook Developers environment.
