DOH! CTM was not enabled. For some reason, I thought that CTM On/Off was included in one of the mapped keys. I added a CTM On/Off to my IWT and it works now.

The only problem I'm experiencing now is occasionally my melee decide to run away after the target is dead. I remedied this by using Jamba Follow after combat. Is there a better alternative for this or is that what you use to make sure your IWT Melee doesn't run away?
