Make sure you don't have other ThickBox loading. The wp_enqueue_script is the safe method for including script files into WordPress but some plugin developers are not using it. Ask who develops your plugin to modify it by using wp_enqueue_script and wp_enqueue_style.
The plugin enqueues the jQuery version included in WordPress. As of version 2.7 WP includes jQuery version 1.2.6. But WP 2.3.2 includes version 1.1.4 so it will probably be ok. I haven't tested ThickBox with jQuery 1.3 yet. The version included with WordPress is safe to be used along with scriptaculous, mootools and other libraries.
