web browsers

Window.event does not exist in Firefox. Different browsers have different event models. Firefox handles the events slightly different IE and Chrome and for that reason it has not worked. A work-around is to pass the event as an argument to the function:
<a onclick="testfunction(event);">
 //...
</a>

testfunction(e){
 evt = e || window.event;
 //...
}

or use a library like jQuery to avoid dealing with all the differences between the browsers.

While the window.event was correctly evaluated on Chrome and IE, Firefox gave the error "ReferenceError:Event is not defined".

Usage of gwt-fx with not mozilla based browsers

<p>Assuming we want to move a specified element from point A to point B, where A and B are absolute positions relative to aparent -element described within a linked css-style sheet;</p><p>(e.g. elementStatA{position:absolute;top:0;left:0}</p><p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; elementStatB{position:absolute;top:10;left:10}</p><p>&nbsp;NmorphStyle will accept the two selector-names as parameters and interpolate the values so that a smooth transition can be displayed; however the whole undertaking will fail (without notification what so ever) if the browser of choice is ie8 (or less), and the html is rendered in strict mode.</p><p>&nbsp;</p>
