Is it only me or the java uploader is acting funny?

[Cypher]

I'm trying to upload a couple of scans,but there's something wrong with the java uploader.
When I press the upload button,the progress bar rush to the end and says "upload finished,processing" and then just halt.
I'm using windows 7 x64 and firefox 3.6.Maybe it's a problem of the x64 version of java?
EDIT:Oh,forget to say that I'm using a 56kb upload ADSL connection,so the rush of the progress bar is abnormal.
