I just installed the plugin:
http://wordpress.org/extend/plugins/wp-prettyphoto/
I have two problems that I found in the forum, and each one said "will be fixed with a release coming out tonight/tomorrow". I am assuming the plugin above included this update?
Problem 1:
Vimeo videos pop up in the overlay, then start auto playing - but only a sliver of the video is displayed. The overlay appears to be the correct size - but the actual video doesn't expand though the whole overlay (the close button is at the top of the box). This is the case in FF and IE8.
Problem 2:
In addition to the problem above - when the overlay is exited in IE8 the music from the video continues to play.
I am not sure if you fixed this and the update wasn't applied to the WP-prettyphoto plugin or if something else is going on.
OK Fixed. It was the WordPress plugin being outdated. To fix just disable the wp-prettyphoto plugin, download the latest package from no-margin-for-errors.com, and install manually into your theme.
