Truncated Text's links don't working properly

Hi, I have a problem similar to scubadiver's one, but the solution that Jane proposed him doesn't work for me. <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=question&id=11895&image=1&table=forumtopics' class='bbc_emoticon' alt=':(' /> So here is my problem.
Im using mediumtext fields (about 100.000 characters each one) on one table, I want to truncate them when showing it on my page. So I checked "Truncate large text fields (More...link)"(80 characters to display) on the miscellaneuos menu. The problem is that this only works for the first entry of the table. If you click the links of the other entries the pop-up window shows the complete mediumtext of the first entry, not their own mediumtexts. What bugs me the most is that the option still works if the texts on the other entries -that are not the fist one- are smaller than 200 characters, but obviously, if I want to truncate a text is because it has way more than 200 characters... <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=question&id=11895&image=2&table=forumtopics' class='bbc_emoticon' alt=':(' /> As a side note, It also doesn't work if the mediumtexts fields contains ramdom german characters like "ä" but it is a minor problem.
Thanks in advance.
