Weird Camera movement when using Mouse Map

Hi

Basically, i use the mouse map so that whenever i click a mouse button on the master it triggers a key (F11) on the slaves.

whenever i map either mouse button, I get a weird behavior when driving on the master.
Basically, clicking both mouse buttons to move the master toon, the camera becomes very very quick, and any slight angle will result in the camera doing a 180+ degrees turn.

this all stops as soon as I remove the mouse map.
Happens with either mouse buttons (right or left or both)
