Sticky Post??

This is what the instuctions say:
# You can configure WP-Sticky options in ‘WP-Admin -> Settings -> WP-Sticky’.
# You can find the post’s ‘Sticky’ Option under ‘Post Sticky Status’ Options in the ‘Write/Edit Post Screen’.

Also note that 2.7 has native sticky post ability.

I have a problem with this plugin. First it seemed to work but the sticky marked post isn’t sticky anymore when I write a new post one or two days later. If I’m writing a new post the same day or like that there’s no problem.
