Problem with loadVars

Hi there, hope anyone can give me an explanation to this, Im using the loadVars for a lets say, a news menu… Each time you click on one button, it loads news from a single .txt file into one dynamic text field. There is only one single .txt file for all the news and one dynamic text fields that displays them…
It works, the problem is that if you scroll down on one of the news, and then you click on another news button the text loads as if it had been scrolled down, where the previous scrolled down left i assume… I imagine it has soething to do with cleaning the variables or something, but cant really figure out, any ideas?
Cheers!
