I just installed phyloviz on my Mac (running with OSX 10.8.5). Uploading the typing and isolate data etc is fine, analysis works, but I can't export the graphics. There is a button with a camera, if I click on it, it says "export view as…." but I can't choose a file format, change the directory or do anything and it gives me an error message. I have attached a screenshot and the log of the error with trying to export a graphic.
