Cannot resize partition

Hello,

Mac 0S X 10.6

I have free space that I would like to use for my MACINTOSH partition. However, when I drag the corner and click apply it doesn't resize and goes back to the original size.

If I just drag just half of the free space I get this message. "MediaKit reports partition (map) too small."

The free space used to be a boot camp partition. As I don't need it anymore I decided to remove by clicking the minus symbol. That worked ok. However, I don't know how to resize my first partition to make 1 partition which will take up the whole HD.

I have uploaded a screen shot of my disk utility.

Many thanks for any suggestion.
