Thread:Extension talk:MsUpload/Upload only working once in Safari

The extension allows me to upload one file correctly. After this it will not upload any more files. It says that the file is uploaded correctly, but does not actually add it. Similar behavior it sounds like as the "Upload is not working" discussion from a while ago. If I clear the cache on safari it will allow for another upload and then stop working again. Safari version 6.0.1.
