[Plugin: Random Posts from Category] widget dropdown not working when editing options

The widget options the dropdown box which allows one to chose title or title and excerpt etc, seems to work ok the first time, but thereafter is not editable – maybe a bug with the way it retrieves any existing options and displays them?

Would also be nice here to be able to choose excerpt only (without the title)
