If you click on a URL pointing to a PDF document in a Word document, a progress bar appears at the bottom of the application. It says “Word is preparing to load this document:”. The bar then takes a few seconds to fill up, during which you are thinking “okay, so Word is going to load the PDF inside an actual document, right?”. No. Because after the progress meter is completed, up pops the PDF document in your browser.
What on earth is happening in between the time you click a link and when the browser opens? What is Word actually doing that requires a progress bar?
Stumbled upon this link via Google as I, too, am wondering what the heck Word is doing when it says “Word is preparing to load this document:” after clicking on a URL. Did you ever figure this out?
