Microsoft已经通过其支持门户报告了很多次这个问题的变化。 以下是一个帖子，如果您向下滚动您将看到一个注释与一系列其他报告，所有详细说明类似的（ish）问题。

Microsoft have had variations on this problem reported quite a few times via their support portal. Here is one post and if you scroll down you will see a comment with a bunch of other reports all detailing similar(ish) problems.

Microsoft似乎不能再现问题，但是将所有类似的键盘锁定问题转换为中心错误，以便我们可以考虑在必要时记录事件的方法。这似乎是一个通用的响应很多这些帖子。有些人报告说，这是简单的因为另一个窗口/窗格/标签是重点，但我可以看到OP显然没有这个具体的问题。看起来像是那些随机无法解决的错误。希望我从来没有得到它！在互联网上还有许多论坛帖子，用户表示删除某些第三方插件可以解决这个问题。

Microsoft doesn't seem to be able to reproduce the problem but are "duping all the similar keyboard locking problems to a central bug, so that we can think a way to log the events if necessary". Which seems to be a generic response to a lot of these posts. Some people reported that it was simply becuase another window/pane/tab was in focus but I can see the OP obviously did not have this specific problem. Looks to me like one of those random unresolvable bugs. Hope I never get it! There's also numerous forum posts around the Internet, where users stated that removing certain 3rd party plugins has solved this issue.

我发现了此特定帖子，其中可能有有用的注释（也可以链接到此SO帖子

I just spotted this particular post which has a possibly useful comment on it for you (which also link to this SO post. As I do not have the bug I cannot test its validity for you. The main point of it seems to be something about the keyboard layout switching.

我是一个非常有用的工具，对不起，把所有这一切都回答一个技术上它不是一个答案，只是一个大量的研究，但没有办法这将是适合一个评论。还抱歉，很多链接垃圾邮件，但再次没有办法我可以提取他们对这篇文章说的一切。我希望有一些有用的东西给你：）

I'm sorry for putting all this into an answer when technically it is not an answer and just a mass of research, but there was no way this was gonna fit into a comment. And also sorry for pretty much link spamming, but again there was no way I could extract everything that they said into this post. I hope there is something useful in there for you :)

编辑：你应该检查下面评分最高的答案这似乎解决了一些人民的问题，虽然我从来没有Resharper插件，并仍偶尔经历这一点，但现在我在VS2013，没有这个问题重新发生，所以也许他们固定它...

You should probably check the top rated answer below as this seems to solve a number of peoples issues, although I never had the Resharper plugin and still occasionally experienced this, but now I'm on VS2013 and have not had this problem re-occur, so maybe they fixed it...
