Hey what you think? That I like to spend time registering on a forum just to post a fake problem? Problably there are people doing that, but I don't see the point. Anyway it is easly reproducible. I've just said what happened to me. Whether you want to fix it or not doesn't depend on me. Maybe it doesn't matter for you couse you don't care about the people that use utorrent and the webui. If that's so your opinion isn't that important. The point is that, for what I have seen, webui version 0.381 can't be installed on old versions of utorrent (<= 1.8.5 I suppose). It looks like a relevant information if it gets confirmed. Maybe other people could benefit from knowing that. I'm not saying that you must fix it. I hope you'll fix it for back compatibility, but that's your choice.
