When choosing File > Save Project As, shouldn't you get a field for the name, in case you want to update the name or change it in some way? I don't have that, and I'm pretty sure it's something I used to have.

Make sure "Resizable File dialogs" is checked in Options>Global

And then you should be able to make the name field visible.

Thanks, I'll check that.

Ok, I just checked it, hopefully that should fix it. What is OpenMP btw? Something to do with multiprocessing?

Yes, it lets A:M use more than one core for certain things, none of them "rendering" I'm afraid.

Cloth simulations speed up quite a bit with OpenMP enabled.
