unable to save file from ethercalc interactive tool

Hi folks, I am playing with the ethercalc IT on live.usegalaxy.eu - it boots up fine and works but I seem to be unable to save the resulting csv/tsv as a galaxy dataset. Can someone please verify this?

The save button works, it gives me the dialogue, but clicking on save format does not create a new dataset. Just a 204 request to IT_url/galaxy.csv
