Validate duplicate files per form, not per MultiFile


What steps will reproduce the problem?
1. build a web form with 2 or more File Uploads
2. in the onFileSelect, add validation that no file name may be repeated in any 
other MultiFile on the same form.
3. add any pdf in one MultiFile, then add the same file to the other MultiFile.

What is the expected output? What do you see instead?
  When it's a repeated file in the same MultiFile, validation works fine, and the file upload is reset.  If you add the file to the other file upload, the onFileSelect javascript works, returns false and the file upload is cleared.  However, the file is still added!

What version of the plugin/jQuery are you using?
PLUGIN VERSION: 1.4.7
JQUERY VERSION: 1.4.4

On what browser(s) or operating system?
BROWSER(S): IE6 & IE7

Please provide a link to where the problem can be observed:
URL:  Sorry... internal.

Feel free to provide any additional information below.
  This is the abbreviated onFileSelect for the 2nd MultiFile:

onFileSelect: function(element, value, master_element) {
  if(fileValidation()==false) {
     this.reset;
  }
})

The fileValidation is simple javascript that checks the file names, and returns 
an alert and return false; if a file name is repeated.

I've tried:
  return fileValidation();
  this.reset & return false;

And many other variations, with no luck.

Any ideas?

Thanks, in advance!
