I really like your plugin and so far i experience 2 problems with it that are really annoying.
1st (and more important for me) is that arrows for next/previous event don't work on the popup window. I believe it could be a conflict with the theme or another plugin.
2nd problem is that in the options page, none of the border width scrolls moves. I cannot set borders different from the defaults. The transparent/opaque scroll doesn't work also. Neither works the lightbox.
Any help will be appreciated! website - http://manataikeranov.com
