Help w/multiple .txt files loading into flash

this should be a simple fix - i can’t find any thread that has encountered this problem so here goes:

the situation: i have a dynamic text box working correctly: it’s a multiple-item menu with a single text box so when you click on one of the four menu items, the respective .txt file content displays in the dynamic text box.

my problem: the first click works - the .txt file displays from the first line (and then however much can be seen in the window). however, if i scroll down through the text (say I scroll halfway through and the uppermost content disappears) and then i click another menu item, the subsequent .txt file displays the new content at the same spot (ie: halfway through the content) so that the first portion of the text is not at the top of the box as you would expect it. if i scroll all the way back to the top and then click another menu item, the .txt file will display the top line(s) of content correctly.

the function works properly in the actual .swf file, but when i play it via the .mov or the .html file output, it doesn’t work…

my question: is there a simple ‘refresh’ function i should be using in the A/S that assures the user will always see the top of the .txt file when clicking a new menu item? my current A/S is simple - each button has the following code with the appropriate .txt file name inserted:

on (release) {
this.loadVariables(“text_terms.txt”);
}

thanks for any help!
