I have made the following javascript to be used in my jQuery based website. What it does, is to move a slider up/down, and scale the item above higher/smaller.

Everything works fine, but since the slider is only a few pixels in height, and the move event is a bit slow (it does not trigger for every pixel) so when I move the mouse fast, the slider can't hold on and the mouse get's out of the slider item. The mouseMove event won't be triggered no more since it is bound to the slider. I guess everything could be fixed by setting the mouseMove global to the whole site, but it won't work, or at least I don't know how to make that work. Should it be bound to document, or body?

here is my current code for the slider:

$.fn.resize = function (itemToResize) {

MinSize = 100;
MaxSize = 800;

pageYstart = 0;
sliderMoveing = false;
nuskriverHeight = 0;

this.mousedown(function(e) {
 pageYstart=e.pageY;
 sliderMoveing = true
 nuskriverHeight = parseFloat((itemToResize).css('height'));
});

this.mouseup(function() { 
 sliderMoveing = false 
});

this.mousemove(function(e) {
 if (sliderMoveing) { 
  (itemToResize).css('height', (nuskriverHeight + (e.pageY - pageYstart))); 
  if (parseFloat( (itemToResize).css('height')) > MaxSize) { (itemToResize).css('height', MaxSize) };
  if (parseFloat( (itemToResize).css('height')) < MinSize) { (itemToResize).css('height', MinSize) };
 };
}); 

};

Thanks for any help, is much appreciated
