[jQuery] ajax issue with ie6 ie7 ?

[jQuery] ajax issue with ie6 ie7 ?

Hi,
I have this ajax call:
$.get("/cgi/check", function(data) {
        $("#check").append(data);
 });
as part of my local home page. The first time this loads on IE6 , IE7 it prompts an "Operation cancelled" alert, but later viewing/launching of the home page do not cause this behavior. This works ok with FF2. Any ideas why this might be ?
Thanks
jose
