Office Reminders isn’t reminding me.

Office Reminders isn't reminding me at all. Unlike Office Notifications in Entourage, Reminders in Outlook never pops open on my screen at all, much less the reminder-in-advance time. Yes, I have it turned on, the time is right and the calendar is right - all settings available are correct. But Reminders does not pop open on my screen, ever. Not when I wake the computer from sleep and not even when I restart. I have to remember to click it to see what's coming on my schedule, and I have actually missed appointments because of this. I could rely on Notifications - Reminders is utterly unreliable. I've looked everywhere I can think of for a setting that will make it pop open, but can't find anything. My wife's Reminders works just as it should, so what's wrong with mine?

I miss Entourage.
