Can't sign in, download, or save.
I started a project and didn't realise I wasn't signed in but when I try to sign in (after I enter my email and password exactly the same as they are) it goes to a blank white screen. It only says "Sign in - GeoGebra" in the top left. When I press "Download as...", choose GeoGebra file .ggb, and click save, it doesn't pop up windows explorer to choose where to save it. When I export image to my clipboard it works, and when I download it, the windows explorer pop up opens but when I save it, it doesn't appear in the file.
If I go to the Manuel, GeoGebra Forum or Report Bug, I'm already signed in, however, if I go to About / License, I'm not signed in, and when I sign in (after I enter my email and password) it goes back to the About / License page (signed out).
There is also a 4 second delay between anything I do or click in the program.
This only happens in this window though. If I open another GeoGebra Classic or on another computer, everything works, downloads, and is signed in.
