Visual Studio 2010: Editor stops responding to keyboard

Question

I\'ve got this very odd bug that appears to be a quirk in Visual Studio 2010: Sometimes, when moving the cursor into double quotes of a CSS style=\"\"

Answer 1

Just encountered the issue in VS 2012, in editing C#.
I noticed that the problem had occurred soon after the trial period of Resharper has ended and i inserted a valid license number. It also happened in only some of the source files.
The solution: Tools->Options->Resharper: Suspend.
Try typing - should work now.
Then: Tools->Options->Resharper: Resume.
Problem gone.
