Strange keybind

Today, my main have a strange keybind. When I press 1 for dps and the slave dps keys....it becomes auto invite to the slave.

I have check the wow keybind where 1 is bind to 1 and no other macro at all and I have also reset to default keybind but the problem still exists.

Can anyone help me what is the possible area where I can unbind the 1 key to become auto invite the slaves.

PS. I have also check the ISBoxer invite, and there is no key bind to 1. Even my slave button 1 become senting out auto invite.

Problem solved.

I have look into ISBoxer key bind and the dps 1 keymap is different from the rest. I am puzzle as I have not change anything on that key. How can it change by itself? to a invite keymap.:confused:
