KB00042 - I have a sticky which keeps coming back? How do I get it to go away?

This is a sticky you've set to recurr, maybe on a daily basis. It keeps coming back because you told it to! Right-click the task-tray icon, and choose Manage, then click on the Recurring category on the left. One of the stickies in the list which appears to the right will be your recurring one - right-click it and choose Close to stop it coming back again.
