Bukkit

What steps will reproduce the problem?
1.Open the hub
2.Click on an item in slot 5 or higher

What is the expected output? What do you see instead?
I expect the command to be runned but nothing happens. If I click on an item in slots 0-4 (which are also the only ones used by default) it works, but all the others don't. Even if I'm opped, those items don't work so it's not a permission problem.

What version of the product are you using?
v1.1

Do you have an error log of what happened?
No. There's nothing in the console.

I've fixed the major issue, and now this is happening to me :(
