Small and tiny files ( < 1MB ) upload fine. Large files won't upload. I have both my file upload limit and my php.ini file max. set to 1000M ( i.e. 1 GB ). But trying to upload a 0.904 GB file has now been hung for six hours. Running Drupal 6 on a 1and1.com Windows server. Locally, I'm running Firefox 15 over Windows 7 Pro 64-bit.
