flash player security

I can run the following locally on my own machine without problem (and also loaded through a test.html. However it will not load if I download it from a test w开发者_Python百科ebhost I'm using.

<?xml version="1.0" encoding="utf-8"?>
<mx:Application 
    xmlns:mx="http://www.adobe.com/2006/mxml" 
    xmlns="*" layout="absolute"
    >

    <mx:SWFLoader id="swfloader" source="colorpickerexample.swf"  height="200" />

</mx:Application>

The strange thing is, I have a much much more complex flex app with all sorts of swfloaders in it which I can download from the test server and run on my local machine without problem. I take it this may have something to do with crossdomain.xml, or trust files or some other aspect of flash player security which I admit I have never properly grasped. So would anyone mind telling me what the flash player is balking about when I try to download and run the above from a test web server.

The source passed to the SWFLoader is a relative path. When you download the SWF to your local machine do you have the colorpickerexample.swf in the same directory?

I apologize, it was case-sensivity - the file name is ColorPickerExample.swf, not colorpickerexample.swf

I don't understand this either, as that's not an issue with the local file system, in case anyone can inform me what aspect is case sensitive here.
