When I finish researching a tech, sometimes the smart tag that displays the detailed information doesn't appear when hovering over that tech in the "select new tech to research" dialogue box. This will go on for a while and then it will work again. This problem also appears when viewing the tech tree as well. The smart tag for the tech will work and sometimes it won't. It would be nice if the smart tag for the techs work all the time, thanx. This problem was also occuring in the v1.51 patch too.
