Tooltip_GC with Mootools 1.2

Hi There
First: I love this Plugin, because it's so easy to handle and brings a very nice effect to my website.
But I have a problem: I must use Kunena Forum 1.6 which needs Mootools 1.2. But when I enable Mootools 1.2, the tooltips won't appear anymore
Can anyone tell me how to solve this?
Thank you very much!

I have Joomla 1.5.22, Tooltip_GC 2.1, PHP 5.2.3

Kind regards,
Dave

tooltipgc for joomla 1.5 is compatible mootools 1.1
tooltipgc for joomla 1.6 is compatible mootools 1.2

so you can take the script of joomla 1.6 to replace it in joomla 1.5 version to be compatible mootools 1.2

Thank you very much. So simple and it works perfect!
