Xml update issue

ok so i built a nice little CMS that is all XML driven, everything working pretty smooth you can open the documents edit them same them, make new ones, and so forth.

the only issue that im hitting is that it will take the app some time before it understands the xml has changed.

so i built a refresh button, it removes all of the listeners nulls the two xml lists then rebuilds everything, but this will only work after sitting around for a minuet, if i refresh right after i add content or make a new file, it won’t show. this isn’t a huge issue since the files do eventually update, but i would like to figure out what is going on,

is there some special way of clearing out an xml in flash?
or is it in the cache?
