It is working and extensively tested by our continuous integration workers. Are you using the latest release [4.7-1](https://github.com/FreeFem/FreeFem-sources/releases/download/v4.7-1/FreeFEM-4.7-1-win7-64.exe)? What are the problems you are facing?

I just tried again right now on my machine. As you can see below, no problem whatsoever.

It also works in parallel, as you can see below.
