How are you embeding generated swf File? using default Flex template?
can you post content of html file that creates swf file?
One test would be to create another project with "Hello World" and swap its SWF in for the one that isn't working. That will give you an idea of it is HTML/Browser-related or app-related.
Another test is to comment out large sections of the app.
Hopefully you use source control so it is easy to rollback to previous changes/versions.

Thanks for the replies, and apologies for not getting back to people sooner. I have been busy deployiong other (flex) apps and setting up an environmernt for working on this problem.
In any event: I have set up a local test environment that enables me to create a deployment and run it on a local Tomcat server. I also found an older version of the application that actually worked without problems before.
I am currently running tests, using Firebug (as suggested) to look at what is happening. I have also swapped in and out enough of the .SWF files and the .HTML files to determine that whatever is causing the blank pages has something to do with my .SWF file. It turns out that my HTML files are not effecting anything (they were generated by Builder anyway, so I am not surprised to see that older versions of the HTML file which worked well with old SWF files show blank pages when used with new .SWF files).
I am in the process of doing more testing so I cannot say much more. I will return when I have more useful information...
I think I have found a big part of the problem.
The system seems to be failing to find a "crossdomain.xml" file on my system, despite the fact that this file exists on my system.
Can someone tell me how to make the application actually find my crossdomain.xml file?
Place it under root of your domain
