Well, Java would be overkill, but I suspect that you mean JavaScript ;-)

Ouch! But really, no-one here is likely to want to produce something for 
any one browser, perhaps least of all IE6 which was, and remains, a

I don't know this recipe, but you might want to consider the 
$EnableUploadVersions option. See the docs:

    When set to 1 (default is 0), uploading a file to a location where a 
file of the same name already exists causes the old version to be 
renamed to file.ext,timestamp (instead of being overwritten). timestamp 
is a Unix-style timestamp.

Alternatively, the fix looks like pointing $UploadVerifyFunction, 
at your own function and, probably, calling UploadVerifyBasic() before 
your code - with an appropriate escape for the '' return value.

It might even work in IE6!
