Yes – it seems to cause problems with widgets, also with page editing.
Causes a javascript error / conflict
I found the same – when deactivating it, all problems went away.
I also like this plugin, so hope an update will be on its way.

Thanks to joshguss there is a fix that might work for some:
http://ww.wp.xz.cn/support/topic/smart-slideshow-widget-broken?replies=5
And here is an alternative plug-in that works just as well: http://ww.wp.xz.cn/extend/plugins/vslider/
Issue is that smart-slideshow-widget.php calls for an outdated jQuery-ui script, which conflicts with changes made in WP 3.5. The plug-in should instead use the jQuery scripts that are included with WordPress.
So replace
(around line: 413)
wp_enqueue_script('jQuery-UI-Effects', WP_PLUGIN_URL . '/smart-slideshow-widget/js/jquery-ui.min.js');
with
wp_enqueue_script('jquery-effects-core');
At least with the other plug-ins I’m running with the Smart Slideshow Widget, the above edit fixed the Widget Page, Media Library, and Add Media issues.
