You could use my usual method..
Simple Algorithm below:
on dragmove {
if obj.dragmoving {
return; // if we are doing a drag loop we can cancle this drag loop
}
obj.dragmoving = true;
dragmove-code;
obj.dragmoving = false;
}
The idea is to prevent the drag code from being executed if it is already in
the process of being executed.
On my old demo this smoothed draggin out a LOT especially on a slower
machine we test with.
