It seems the Google translate proxy test is broken, it's reporting 100% failed proxies, but when I use them to translate (without testing), there's no problem and everything is translated fine.
Also, SER keeps collapsing groups of projects that I don't want to be collapsed. When I save a project, groups are collapsed. When I close and re-open SER, groups are collapsed. Is there some config file that causes this? Why does it happen?
