Really ackward Poll problem with my vbulletin 2.3.4
 

In forumdisplay.php the thread starter is the one who started the poll and the thread, that's normally ofcourse... But the problem I have is that the first person that replies to that poll & thread, he will become the thread starter in the forumdisplay threads list. And that shouldn't happen ofcourse.

You can view the problem in 'action' here:
There is a thread (in my poll section) called: Which nationality of prince fans is the most? As you can see "ivy1213" is the one that started the thread/poll:
http://www.housequake.com/showthread...threadid=26135

But when you look at the forumdisplay the first person that replied (hoinszj) is suddenly the thread starter:
http://www.housequake.com/forumdispl...?s=&forumid=31


Does anyone remember this problem, or can push me into the right direction to fix this?

Thanks people!

Nobody has an idea what it could be? Or recognizes the problem?

Pointing into the right direction would be very helpfull too! :-)
