Disk Partition Problem

[dumb]

I have OS X Lion and a Bootcamp partition, I had the other day resized the OS X partition to create a shared partition. Now, I no longer need the newly created partition, so i deleted and wanted to merge with the OS X partition but nothing seems to happen when I drag ( bottom right corner).

I also went to Lion Recovery and Disk Utitilty, but no luck. As far as I understand, it may not allow to expand, as OS X cannot be mounted but why allow resizing and not extending.

Here is the screenshot of my partitions. Thanks for the help.

You need to use a third-party partitioner, like iPartition or Drive Genius.

Thanks will check it out...or may end up formatting OS X partition and reinstalling lion.
