[jQuery] Error creating div in IE7

[Márcio Kabke Pinheiro]

I'm very new in jQuery (in fact, only 2 days :-) ), and I'm having a
strange error in IE7.

I have a little JS function that, when a link is clicked, creates a
div in the screen and shows a PHP page created with an parameter
passed. Nothing too fancy, is like a pop-up window.

The code is really simple:

function callDoc (cod) {
   $("<div id='document' class='document'> Loading document...</
div>").appendTo(".maintable");
   $.get ("document.php", {doccode: cod}, function(page){
          $("#document").html (page);
       });
}


Works like a charm in Firefox, but nothing appears is IE7. Since I
don't have a Firebug in IE (anger...), and no error appears in the
IE's status bar, I've inserted and alert ("Hello") in the first line
of the function, to see if the functions was been called. It appeared.
Then, the problem is in the jQuery commands.

To make it more strange, once in a while (very few times) the div
appeared in IE.

Any hints? Rookie mistake? I have to finish this site 'till the end of
the week.

Sorry for my English, and thanks in advance
