Re: Cannot type in a input type="text" with border radius se
Thanks for reporting this issue! Yup, there are definitely issues applying PIE to input elements. We've had bug report http://github.com/lojjic/PIE/issues#issue/36
opened already, which sounds like what you're seeing.
This will get addressed in a future release. For the time being I'd suggest maybe wrapping your input in another element and apply PIE.htc to that wrapper instead, and set the input so it has no background or border. A bit hacky, I know, but it should at least get you through for now.
