Here's how it all went down. DKs have Death and Decay bound to a key with send next click. So I press the keybind [so all windows now have a mouse cursor] and then press the mouse repeater key and the mouse cursor goes away [but mouse repeater thinks it's still active]. Now the mouse repeater is opposite. When the cursor shows in all windows it's not really doing it's job. When the cursors go away in my slave windows it's really there.

Not sure if this is a known bug or not but I figured I'd point it out.
