I'm using a newly downloaded and re-installed version release v6.5.1. After I launch the desktop app, I usually click the Login button on the top right of the app, then click on the Google button to log in using my Google account. After that, the desktop app usually comes back and I'm logged in. Now, after clicking on the Google button, the program opens a new (web) window with the home page for EasyEDA. Closing this window and going back to the desktop app leaves me not logged in. If I click on the Project icon on the left (in the desktop app), then click the green "Login" button there, the same process happens. I can log in to a web window, but not the desktop app. While I can use the web windows for now, I'd much prefer to have the desktop app back (which I realize is just an app to host web calls anyway, but fine).
