inability to upload

having just added a few miles of tracks onto the map

I am now unable to upload the tracks, it just stops and says Uploading… Uploading ways
How can i get the data uploaded?

Having just checked from another page most of the data has been uploaded but the first page (the one i have been editing from) still appears to be uploading data. Shoul i get some form of confermation message when the upload completes rather than click cancel when enough time appears to have elapsed and then press cancel and hope it was sent.
