Q:

VS2012 javascript intellisense works only with explicit invocation

I am trying to make the new vs2012 javascript intellisense work.
At first I noticed it was not working because resharper intellisense was enabled. I tried to completely suspend resharper, and I got a better situation, but still buggy.
I added the _references.js file with a couple of references (jquery and angularjs). I switched, in the options, to Implicit (web) settings so it reads the _references.js file.
I added an empty js file. Intellisense only appears if I CTRL+SPACE (for method and types list) or CTRL+SHIFT+SPACE (for method parameters list) but it doesn't appear when I start typing, nor when I type a dot or open a round bracket.
I don't really know what's the problem. Resharper is out of the way so everything should work.
The edition is Vs2012 premium 11.0.50727.1 RTMREL.
Other extensions installed:

Web Developer Tools (which I also got on a web developer express edition on another computer, and on that installation intellisense works fine)
Web Essentials 2012 (disabled) 
Visual Studio Extensions for Windows Library for Javascript (which I can't disable nor uninstall)
Git Source Control Provider (which I hardly think could be related)
xUnit.net runner for visual studio 2012 (again, hardly related)

Thanks.

A:

ReSharper intellisense and Visual Studio intellisense are two completely different beasts.
If you have problems with ReSharper intellisense, then please describe what kind of a problem do you have with it. Does it work with Ctrl-Space? If it works, but it doesn't get invoked automatically, then please check settings at ReSharper | Options -> Environment | Intellisense | Autopopup.
If you prefer Visual Studio intellisense, please go to ReSharper | Options -> Environment | Intellisense | General, select Limited ReSharper intellisense and turn off JavaScript there. Then ensure that Tools | Options -> Text Editor | JavaScript | General -> Auto list members is turned on.
