I am running version 1.4 on Windows 10 and have noticed 2 issues.

1. The check update functionality is not working. I get an error saying "An unknown error occured while trying to search for updates: SSL/TLS support is not compiled!"
2. The most important, the app has placed a file-write lock or changed some permission of the hosts file because now I can't edit it to add my own entries. I am used to adding entries used for web-deving, now I can't. Even if I disable the 'immunizations' I still can edit the host file, not even as an administrator.
