I am trying to click down on a window but no matter what i do it clicks down but then doesn't hold it. shouldn't this If GUICtrlRead($Maxx_Boost) = $GUI_CHECKED Then MouseClick(333, 295) MouseDown("left") later on in the script i send a mouseup("left") command but it doesn't hold until then. I'm not sure whats wrong Additionally if someone thinks they can do this i would be impressed. Insert a slider that is possible up and down not left to right? If the slider is all the way down clic
