Normally when I click on a file in IE9, the download popup shows at the bottom of the screen either asking me to save/open/cancel or shows download progress. Randomly, when I click on a file, it won't do anything at all. But if I sit and stare at it doing nothing at, it'll eventually pop up and ask me to save/open/cancel. It doesn't matter if the file is 8MB or 8KB. The browser isn't unresponsive, just the download manager.
