Definitely a PIA but is the best approach I have so far.

So far, closing the Windows app (say "yes" when it warns you), canceling the attempt by Windows to "resolve the issue" then restarting the app (from a pinned icon in the Windows 8.1 task bar-I only use Desktop mode) it comes right back, and my last operation is complete. I have seen it mainly when trying to copy/paste between notes, but that is not definitive as a cause. In my case, I get the "Not Responding" thing when doing operations in the Windows 8.1 application. If anyone finds a solution or workaround I'd love to know. You can see some related discussion on this in another thread: Unfortunately for those of us using Windows, at least for Windows 8.1 there were a bunch of updates in the past week which may also have created some issue. (275519) Public, but seeing the comments above I realize that might well be it. I'm unsure if it is precisely correlated to installing 5. I am having frequent crash issues in Windows 8.1 since a couple days ago.
