Hi Sancho, We don't have a Mac to test now.

It’s not the Mac: a) Without being logged in I can’t save, I don’t see my test project. b) Logged in I see my test project, but I still can’t save, as reported with Firefox (“create project …”).

Tried again: A) Not logged in: 27.9. _Now_ OS X Safari can save anonymously and can print the schematic. < I’m not sure if I’ve tried that before, I don’t think so because I’d not have expected that it would be allowed without login and later from dillon’s comment “you have to create a project first > B) Logged in: - 27.9. Still, OS X Safari can’t save to the “Anonymous Files” without any error message, on the contrary, it indicates “loading” for a second ===> which is a wrong text !!! = You could say “transmitting” or “connecting”, but “loading” is misleading = but I don’t get the “success” pop up (this is a nice feature, thumbs_up) and the schematic is not there. Of course I can not print it. - 27.9. Still, OS X Safari can’t save to my user project because of error message: “This file must be saved under a project, choose other project or create a new project - OK”

Hi, Try to reload the web site twice, We think you can save your file to your project now. Yes there is a random bug. Very few chance to happen. Sorry. When you login and you can't save your file to “Anonymous Files”, it is strange also, we can't suffer this. Please try it again and we will try to find this. Thanks.

… it was not randomly (?), however: OK, it is fixed now, can save when I’m logged in with Safari, thanks. Will try FF on OS X and Linux later (but I’m confident!).

Hi Sancho , It is really randomly . When you create a project, you will get a random project id. But your random project has a bad letter, this make you can't save your files under your project. It is in very few chance to get, but you get it. :). So no matter which OS or browser you use, you can't save your file under this project. Now we fix it. Many thanks.

So randomly, OK. Well, if there is sh** I will stumble across it, that’s my fate and an important part of my making money ;-)
