Can't edit StickIt note

One of the StickIt notes I have on my desktop is behaving badly. When I click in the little box because I want to edit it, I get the following:

Run-time error ‘380’
Invalid property value

I have no choice but to click on the OK. The whole note disappears. It will return only when I shut down and reboot. Then the process starts all over again. I cannot remove or edit the note. Am I doomed to look at this note forever?
