I apologize for you having to update the labels relating to the Polling interval - I realized users may prefer it being in seconds rather than milliseconds, so I may need you to update that again soon. But I'll merge this in now. Good work, thank you!

@MaxMadcc Question for you:

My Visual Studio client persistently wants to reverse some of the changes you made in this commit, do you happen to know why? For example, here's WinNUT.zh-CN.resx:

No matter how much I discard the changes, Visual Studio tries to make them again. Do you know if your IDE made the first set of changes automatically too? Do you think it would break anything if I accepted the changes that my IDE wants to make?

Look like my bad. 😲
I remember I use ResXResourceManager easy to fix translation. It will sync between ResX and Xliff resource files.The content on the image was generated by ResXResourceManager.
I took a look, it's okay to delete it.
