node.js - Express.js app frequently doesn't load new route without hard refresh? -

i'm experiencing strange issue. when navigate page page in express.js app (currently have 3 pages: home, about, contact), page appears blank. when hard refresh on mac (shift command r) of assets load in. when @ networks tab in chrome dev tools, appears if assets loading in -- don't see 404's.

here screenshot of app directory see i'm working with: http://d.pr/i/lqlv

also, here app.js file:

var express = require('express')     , partials = require('express-partials')     , app = express();  app.configure(function() {     app.set('title', ' | todo app');     app.set('view engine', 'ejs');     app.use(express.static(__dirname + '/public'));     app.set('views', __dirname + '/views');     app.use(partials()); });  app.get('/', function(request, response, next) {     response.render('index', { title: "home" + app.get('title') }); });  app.get('/home', function(request, response, next) {     response.redirect('/'); });  app.get('/about', function(request, response) {     response.render('about', { title: "about" + app.get('title') }); });  app.get('/contact', function(request, response) {     response.render('contact', { title: "contact" + app.get('title') }); });  app.use(function(request, response){     response.render('404', { title: "404" + app.get('title') }); });  app.listen(3000); 

you not using app.router, handles routes:

app.use(app.router);   app.get('/', function(req,res,next){ res.render('index'); });
