Delay when loading external text

This pertains to the loadVars method I 've been tinkering with and hope to master very soon.

I’m determined to have my external .txt file load into my dynamic field without ANY DELAY WHATSOEVER.

It seemed like the onLoad method of the LoadVars object would handle this nicely, however it does not work for me.

I placed the following code on the first frame of my movie:

loadText = new LoadVars();
loadText.load(“content.txt”);
loadText.onLoad = function() {
aboutrandi = this.about;
}
stop();

Then further along the timeline, I display content in my dynamic textfield by placing the following code:

my_mc.text = aboutrandi;

It displays fine but there’s still a delay. I figured the content from my .txt file would be loaded by now (its 2KB in size and has html tags embedded).

Am I doing something wrong? How can I properly “preload” my external text?
