When Flash movie is loaded, cache of your browser filled with that flash movie. Problem may occur if you want to update it because flash automatically looks for movie already in the cache. If it¡¯s found, simply will show you the movie without update i.e old version of that swf.

In order to avoid it use the following code:

myVar =Math.round(Math.random()*10000);
loadMovie("mymovie.swf?uniq="+myVar,1);

Here, myVar is simply a variable which occupies random number that will be generated by
random() .
