have to release the mousebutton and click again to trigger another
event.

I'd have to try this in code to be sure but am busy atm.  :-\  Would
something like this pseudocode work?  I forget if an object property
already exists that holds the down state or if so, what it's called.  I
just call it "mouse_down_flag" here.

onmousedown = function
{
    obj.mouse_down_flag = true;

    while ( obj.mouse_down_flag == true )
    {
        move in specific direction;
    }
}

onmouseup = function
{
    obj.mouse_down_flag = false;
}


Also try the CVS copy, as your results may vary from the beta copy.
