In jquery 1.4 and 1.3, loading just the framework definition causes an error, why?

Whenever I load ONLY the 1.3 or 1.4 library on an html page im developing on my desktop I get an error that says "setting a property that only has a getter"

I dont have any additonal code, this is coming straight from the jquery.min.js file

I also get a bazillion warnings in Firebug.

Can someone help me resolve this issue?

I can't determine why 开发者_Go百科this is happening

<script type="text/javascript" src="js/jq/jquery.js"></script> 

just try a simple function call to see if the base is even loaded.

   jQuery(document).ready(function(){
      alert("howdy"); 
    });

alternative, find out if it is loaded (better)

<script type="text/javascript"> 
if (typeof jQuery == 'undefined') 
{ 
    alert('not loaded');
} 
</script> 

Third alternative, since I cannot know for sure if you have the library at the path you SAY it is within: change to :

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script>

EDIT: FOR THE SHORT NUTS OUT THERE: (no typeof needed :)

   <script type="text/javascript"> 
    if (!window.jQuery) 
    { 
        alert('not loaded');
    } 
    </script>
