I just received the latest Automatic Update from Microsoft today. After restarting, it seems to have goofed up Windows Explorer! Now whenever I open it from the right context of the start button and choose explore, it opens with the Start Menu and I cannot click on the [+] open nodes to open any drives or folders. All that happens is an hour glass. I can click on each folder to show the contents in the right pane, but the treeview functionality seems to be gone. Anyone else experience this anomaly?
