calwidget help, how to delete calendars? why does it take forever to update the widget?

[tracerit]

when i go to edit a calendar it'll give me a list of all the other times i used a calwidget calendar. since it's so hard to find which one i used, how do i delete the list of available options to choose from?

also, i added an entry but it takes forever to show on the widget -_-

bump? maybe list another alternative to calwidget? just looking for something simple with a transparent background.
