Don't know how it happened, but VS2013 + NTVS RC2 got itself in a tizzy, and the project as a whole kept trying to refresh itself, over and over. An obvious manifestation of this was if I expanded a node in the Solution Explorer (say the npm node, and its subnodes), then a second or two later the tree would be collapsed, and the project item would become the selected item in the Solution Explorer. I expand the tree... then it collapses, over and over.
Closing then re-opening VS didn't solve. Only by rebooting the machine did I get it to stop doing this. Now I can't repro it... but I thought I'd mention it anyway, in case someone else has seen something like this.
Comments: One reason why I don't want to upgrade all packages to latest without very careful thought is that I've ascertained that NTVS can't show Intellisense for Express vLatest, and so have carefully chosen an earlier version where I can get Intellisense (at least while I'm learning Express). https://nodejstools.codeplex.com/workitem/1789
