Was playing with the cats sequence today. I got the following errors. I think this was due to me trying to use the frame handles to resize the editor areas. (wasn't working). I was using Safari

jui.combined.min.js:71
TypeError: Result of expression '$.widget.prototype._trigger' [undefined] is not an object.
That line contains:

+($.browser.safari&&this.cssPosition=='fixed'?0:(this.cssPosition=='fixed'?-this.scrollParent.scrollLeft():scrollIsRootNode?0:scroll.scrollLeft())))};},_clear:function(){this.helper.removeClass("ui-draggable-dragging");if(this.helper[0]!=this.element[0]&&!this.cancelHelperRemoval)this.helper.remove();this.helper=null;this.cancelHelperRemoval=false;},_trigger:function(type,event,ui){ui=ui||this._uiHash();$.ui.plugin.call(this,type,[event,ui]);if(type=="drag")this.positionAbs=this._convertPositionTo("absolute");return $.widget.prototype._trigger.call(this,type,event,ui);},plugins:{},_uiHash:function(event){return{helper:this.helper,position:this.position,absolutePosition:this.positionAbs,offset:this.positionAbs};}}));$.extend($.ui.draggable,{version:"1.7.1",eventPrefix:"drag",defaults:{addClasses:true,appendTo:"parent",axis:false,cancel:":input,option",connectToSortable:false,containment:false,cursor:"auto",cursorAt:false,delay:0,distance:1,grid:false,handle:false,helper:"original",iframeFix:false,opacity:false,refreshPositions:false,revert:false,revertDuration:500,scope:"default",scroll:true,scrollSensitivity:20,scrollSpeed:20,snap:false,snapMode:"both",snapTolerance:20,stack:false,zIndex:false}});$.ui.plugin.add("draggable","connectToSortable",{start:function(event,ui){var inst=$(this).data("draggable"),o=inst.options,uiSortable=$.extend({},ui,{item:inst.element});inst.sortables=[];$(o.connectToSortable).each(function(){var sortable=$.data(this,'sortable');if(sortable&&!sortable.options.disabled){inst.sortables.push({instance:sortable,shouldRevert:sortable.options.revert});sortable._refreshItems();sortable._trigger("activate",event,uiSortable);}});},stop:function(event,ui){var inst=$(this).data("draggable"),uiSortable=$.extend({},ui,{item:inst.element});$.each(inst.sortables,function(){if(this.instance.isOver){this.instance.isOver=0;inst.cancelHelperRemoval=true;this.instance.cancelHelperRemoval=false;if(this.shouldRevert)this.instance.options.revert=true;this.instance._mouseStop(event);this.instance.options.helper=this.instance.options._helper;if(inst.options.helper=='original')
