Bukkit

What steps will reproduce the problem?
1. Install (place the plugin in the "plugins" folder) Market v 0.9.9b for RB 1.3.2 R2.0
2. Install also WorldEdit (any of the latest versions for RB 1.3.2)
3. Start the server
4. Be sure to be OP and put yourself in creative mode
5. Use the wand to make a selection

What is the expected output? What do you see instead?
When you hold the wand (of WE) and you left-click you start the selection. Normally in creative mode if you destroy a block while holding the wand (wooden axe) it will be re-created after a while (without using Market in the server).
When you use WE and Market in the same server, they conflict.
In fact, when left-clicking to start a selection the block is destroyed but it doesn't come back.

What version of the product are you using?
Market v 0.9.9b

Do you have an error log of what happened?
No.

Please provide any additional information below.
I have tried to remove temporaneally Market from my "Plugins" folder and all worked as it would be. So I think that is a problem inside the code of this plugin.
