JQuery $.ajax problem at safari

Question

Hi all,

I am working on a .net web project (with using c#). there is a drop down list on the page. the drop down list's onchange method calls a jquery function and this function makes an ajax call. with ajax call the handler returns the html of a renderable user control. then the jquery function locates the returned html into page. these operations works fine at IE, FF, Chrome and Opera. at Safari the ajax call goes to handler but does not go back to jquery.

I tried jquery-1.4.2, jquery-1.3.2 and jquery-1.2.6, but all has the same results.

I'll be glad if someone has an answer. Thanx in advance.
