Page doesn't finish loading when running web project (sometimes)


Win 8.1, VS 2013, rolling build CL71479
Create flask project
Create virtual env (2.7), install flask into it
F5 (opens internet explorer)
Sometimes the page will load immediately, sometimes it doesn't (says Waiting for localhost and the query doesn't show in the console)

It happens probably less than 50% of the time. When it does, you can tell IE to stop and reload and it will load the page fine.

Note: Pretty sure I've seen it happen with bottle and flask.
