A common problem when loading variables from a text file, is that you can't do anything with those variable values in the same
keyframe, since the variables might not be loaded yet.
So, my guess is that using an onClipEvent (enterFrame) action for loading the textfile is not a good idea. Or maybe use a timer, to
build in a pause.
Also consider the browser caching the textfile, so updates might not show up, it will just load from the cache. Using a random
number with the loadvariables is a possible solution.
