I was installing some hardware and trying to get 7 to recognize it. I opened my Devices and Printers folder, about 2 minutes after closing it, and the page was blank. The progress bar was moving across the address bar, it moved all the way to the right, and just sat there. I left the page open for 10 min., and nothing changed. I thought it had stopped responding, but the task manager said it was running ok. So what happened to it, and how do I fix it? Please don't tell me to reinstall, I just did that.
