[javascript-dev] cursor position in windows XP

hallo everyone,

i am trying to access he mouse position in absolute screen coordinates from within a jsui object. The wind.location property  returns the coordinates of the mouse cursor relative to the Left Top of the main Max/MSP application window, not the screen coordinates. The reason i need the absolute screen coordinates is that i want to lock the mouse position while drugging inside the jsui. 
Any suggestions ??
