Classic example... I login to the EMR system my GP's office uses, and click around a bit, looking at test results, notes, etc. Then, for whatever reason, I happen to reload the page or click the "back" button. Boom, I'm out of the application and have to login again from scratch. Grrrrr... SPA's and this fancy stuff have their place, but let's not pretend that it doesn't come with a cost.
