My task don't show up on the main screen under the Calendar icon. They show up if I actually enter the calendar (have it set to show task) but not where I can see them from the Home screen. My appointments do show up but not the task. Is there any way to change this? Hopefully I won't have to make all my task appointments just to view the upcoming ones at the Home screen.....

have you tried to do a battery pull after switching to the theme? sometimes events do not show on the theme main page, not really seen an explaination why yet

I have tried a battery pull, no luck

I've never had tasks show up, so maybe they're not supposed to?

Tasks are not calendar items, ergo they don't show on the homesceen calendar

I see you have a 8700. How did you get the today theme for the 87xx?

or in the case of an 8703e with 4.2.1:

I don't believe tasks show on the calender in the Today style themes. I have also noticed that if you add an event to your calendar that is all-day rather than one that has a fixed start and end time, it will not show on the homescreen either.
