I wanted to reduce the file size for a Flex application of mine. I followed the suggestion on this site:

[http://csharksgames.blogspot.com/200…file-size.html](http://csharksgames.blogspot.com/2009/02/reducing-flex-file-size.html)

Basically, I’m now loading the Flex framework swfs externally. The trouble is, this method has caused data in my DataGrid components to turn invisible. The entries can still be selected, but the fields aren’t visible. Has anyone encountered this before? If so, know of any solutions? Thanks very much.
