Hi is there any bug known with jQuery and Opera 10.50b?

I use some part of code under 10.50b and I have some problems to display ajax result. Under latest stable all is OK.

Firebug doesn't show any errors.

It's my code:

2. $.preloadImages("/images/popup-ajax-loader.gif");
3. // Define loader IMG dimensions
4. var ajaxLoaderW = 66;
5. var ajaxLoaderH = 66;
6. ///////////////////////////////
8. var popup_div = '<div class="popup_layer"><div class="popup_layer_bg"></div><div class="popup_layer_content"><img id="ajax_loader_img" src="/images/popup-ajax-loader.gif" /></div></div>';
9. $('body').append(popup_div);
10. $('.popup_layer').fadeIn('slow');
11. // Place loader IMG
12. var marginL = ($('.popup_layer_content').width() - ajaxLoaderW)/2;
13. var marginT = ($(window).height() - ajaxLoaderH)/2;
14. $('#ajax_loader_img').css('margin-left',marginL).css('margin-top',marginT);
15. ///////////////////
17. $.ajax({
18. url: urlParam,
19. dataType: 'json',
20. type: 'post',
21. success: function(j) {
22. $('#ajax_loader_img').hide();
23. $('#ajax_loader_img').remove();
24. if(j.error != 1)
25. {
26. $('.popup_layer_content').html(j.body);
27. $('.popup_layer').fadeIn('slow');
28. var popupHeight = $('.popup_layer_content').height();
29. var popup_div_MarginT = ($(window).height() - popupHeight)/2.5;
30. $('.popup_layer_content').css('margin-top', popup_div_MarginT);
31. $('.custom_checkbox').click(function(){
32. doCustomCheckboxAction($(this));
33. });
35. $('.form_cancel_button').click(function(){
36. hideErrorDiv();
37.    $('.popup_layer').fadeOut('slow', function(){
38.           $('.popup_layer').remove();
39.    });
40. });
41. }
42. }
43. });
