I'm at a new workplace with a new PC with Windows 7 and Office 2010 and get into trouble regularily, since meeting reminders simply stay hidden behind all my open documents and never make it to the top to remind me. In older versions they popped up on top, you could hit snooze and they would pop up again until you hit dismiss. The new menu structure is really hard to navigate and not as easy as in 2003. I found the options menu but there is no check box to force reminders to really pop up. I see this as a serious bug.
