I am receiving the following error when uploading an image via flash:

 

Unable to find the uploaded file in directory: C:\WINDOWS\TEMP\

 

This occurs in Firefox 3.6 and Safari 4. I can upload successfully with Silverlight in IE8, and can upload successfully with the html uploader in all three browsers. From what I can tell, I am running the latest version (6.6), and we are using .Net 2.0. Is there a specific configuration for the flash uploader which I may have missed? Everything else seems to be working just fine.
