HTC Desire :: Calendar Reminders - Dismiss Disappearing

Is there any way to get back to the "Snooze all/Dismiss all" screen for calendar notifications? I've been having major issues with my reminders disappearing before I can dismiss them or after I snooze them. To see what I'm talking about - set an alarm via your calendar (Google, in my case) and try to keep the phone "awake". That screen that pops up will show snooze or dismiss all buttons.

The reason why I need that screen (or at least a consistent way to dismiss the reminders) is because sometimes, odd things happen. For instance, if the reminder goes off and I pull the phone out of my pants quickly, it disappears. I don't know if it dismissed or snoozed. Often, it snoozes because it will ring again. At other times, it will play the notification, but give me no way to dismiss it. I have to power down in order to get it to stop. Talk about frustrating. When it powers back up, the notification shows in the status bar. Then, there are times when it simply vibrates once... repeatedly, but at what seems like five minute intervals. I'll feel it go off, but when I take it out, the phone has no status bar notification.

This is REALLY frustrating because my phone is my lifeline - I teach school and it reminds me when classes start and end. However, I'm a bit skittish now because I go into panic mode when it doesn't quiet or it keeps notifying me.

I have Pure Calendar Widget and Calendar Pad Pro running. Could these be causing any kind of conflict? I really like both of them because the native calendars suck. However, I am willing to let go of Cal Pad Pro if worse comes to worse.
