Multiple file upload with Flex and ColdFusion Problem

Hi all,

I'm trying to resize some images after upload using the "Multiple file
upload with Flex and ColdFusion" at

http://www.adobe.com/devnet/coldfusion/articles/multifile_upload.html

Has anybody actually got a script that resizes images sucessfully
after uploading images with this method?

The reason I ask is I just cant get it to work properly, I've tried
everything I can think of and ended up with the code below. Which
resizes the images but does not remove the original file. The error
that gets dumped is:

"ColdFusion could not delete the file C:\ColdFusion8\wwwroot
\MultiFileUpload\uploadedfiles\0040.jpg for an
unknown reason."

Which doesnt really help. So I try and delete the original files
manually but windows also wont let me and says its been used by a app.
If I upload some more files I can then delete the original files from
the previous upload.

To me it seems like the flash player isnt releasing the file

Any help would be greatly appretiated.

Richard
