Yup, they’re one in the same. Every now and then on XP, when you’re doing more than one task, Explorer hangs, then you get a dialog box stating that Explorer is not responding. You click the button and all your folders are gone, and the taskbar. But it does come back, refreshed and new apparently. Well guess what, Windows Vista does the exact same thing !!!!
Who says there’s a learning curve going from XP to Vista.
