We released an update for WP-Backgrounds Premium (v1.5.0.0).
Changelog for version 1.5.0.0:
Bug Fix for WP 3.3: The new login page messed up our custom styling. Updated custom css file (you only need to replace the css file in wp-backgrounds\includes\inoplugs-custom-login if you’ve made any modifications to the plugin files).
New feature (user request): Fade in effect for the first image (better transition on page load) – you can see the new fade-in effect on the demo page: http://demo.inoplugs.com/.
Plugin should be compatible with WP3.3 now. We noticed a bug with the new WP3.3 media uploader for post meta values. We need to update our post meta class to support the new uploader. The option pages (category/taxonomy/terms/standard pages, etc.) are not affected. We’ll try release an update next week.
