I found a way which works out almost perfectly, but might not well implemented…

Modifications to make :

in tooltip.js :

I added a variable visible=false; that becomes true when show() is called and false when hide() is called.

Then below the hide() function I added my own toggle function :

toggle:function(v,w){
                    if (visible){
                        tooltip.hide();
                    }else
                        {
                        tooltip.show(v,w);
                        }

                }

then in glossary.php add this after the onmouseover and onmouseout events :

onClick="tooltip.toggle(\'' . $glossaryItemContent . '\');"

Onlydownside is if you click on your glossary word the tooltip will disappear even if you are still hovering it. (Links to the glossary page have to be disabled).
