Is anyone else having a problem using Bedside Mode on OS 5.0?

I never used Bedside mode before upgrading to OS 5.0. But I have noticed that since I upgraded to 5.0, my Storm seems to start "up" with the Calendar showing, rather than the main screen.

I am now trying to use Bedside Mode. When I plug it in, it says it is going into Bedside Mode, dims the display, and shows the Clock. Exactly what it should do, and what I want it to do! However, sometime during the night (not very soon, perhaps at midnight) , the display of the Clock changes to displaying the Calendar. When I wake up early in the morning and look at my Storm to see what time it is, all I see is my Calendar for the day.

Why is the display of the Clock changing to display the Calendar? Is this a 5.0 "bug"? Is there a way to display the Clock all night?
