What do you think of the reminders?

Too intrusive?  Do you find them helpful?  Per earlier posts, I created them to mimic reminders I set in my e-mail client to take an action.  I find that they help.  I thought about having a small window open to give the user the option of either opening the reminder or not opening the reminder.  But when I thought about it, the user either has to select a button to see the reminder or select a button to not see the reminder.  The way it's implemented, the user either does nothing to see the reminder or touches a button to close the window.  I figure this implementation  is more efficient.
