<p>There are some elements that overlap the tooltips, such as select form elements and flash animations. DOM Tooltip can hunt down and hide these elements that cannot be overlapped.* The solution is somewhat crude, but necessary in order to ensure the tooltip remains visible.</p>
<p class="note">Note: The collection of elements to hide is cached in a variable <code>domLib_collisionElements</code> on the first tooltip activation. It is possible to flush the cache and force a new search by setting the global variable <code>domLib_collisionsCached</code> to <code>false</code>.</p>
