Double click problem with IE happens when you double click over some
text (years, months, a title...). The timeline then gets the
coordinates from inside the div containing the text, which are too
small, so the timeline tries to go to the start.

I modified timeline-bundle.js son when the coordinates are small,
double click does nothing:

From this:
Timeline._Band.prototype._onDblClick=function(C,B,E){var
A=SimileAjax.DOM.getEventRelativeCoordinates(B,C);
var D=A.x-(this._viewLength/2-this._viewOffset);
this._autoScroll(-D);
};

To this:
Timeline._Band.prototype._onDblClick=function(C,B,E){var
A=SimileAjax.DOM.getEventRelativeCoordinates(B,C);
if(SimileAjax.Platform.browser.isIE){
if(B.offsetX > 100){
var D=A.x-(this._viewLength/2-this._viewOffset);
this._autoScroll(-D);
}}else{
var D=A.x-(this._viewLength/2-this._viewOffset);
this._autoScroll(-D);
}};

Thanks Larry for passing this on! Rather than patch timeline-bundle.js, I 
overrode
Timeline._Band.prototype._onDblClick in my own code, and expanded Xosen's code 
so I
could read and understand it, thus: 

Timeline._Band.prototype._onDblClick = function(innerFrame, evt, target){
  var coords = SimileAjax.DOM.getEventRelativeCoordinates(evt, innerFrame);
  if(SimileAjax.Platform.browser.isIE){
    if(evt.offsetX > 100){
      var distance = coords.x-(this._viewLength/2-this._viewOffset);
      this._autoScroll(-distance);
  }} else {
    var distance = coords.x-(this._viewLength/2-this._viewOffset);
    this._autoScroll(-distance);
}};

I find it odd that there's so little complaint of this bug. Thanks Xosen for 
working
out this hack. I hope it makes it into trunk eventually.
