plugin does not work on protected wp-admin directory

Hello,

Must say – great plugin, simple and easy!

However I have an issue – for security reasons I always password protect the wp-admin directory on my WordPress installations. Your plugin works fine if I have signed into the directory, but for everyone but me, when I try and like a post, a login box pops up immediately requesting login. This is for server-side login to the directory, not login to WordPress.

I’m not prepared to unprotect the directory as I’ve been hacked before… but I want to use your plugin! Have you got any ideas how I can work around this?

Many thanks!
