I can not safe via RRO button in Safari Version 8.0.2 (10600.2.5) on OSX 10.10.1.
When I try to safe via RRO button I get a screen full of tekst (screenshot). But the drawing is not saved with the new name or the previous name. It is gone.
Fortunately the Save button does work.
Diff:
Right. The problem is that Safari does not support the HTML 5 "download" attribute (http://caniuse.com/#feat=download). We're going to need to look for alternatives for browsers that do not support this (among which is Safari). Not sure if we can find a simple way for pure client-side "save as" functionality.
