Cookies makes Ajax ASync treat like Sync

Hello,

I moved an existing project into the CodeIgniter Framework. 

If I try to click on a link during JQuery Ajax Request which is still loading, I can't do anything on the page, meaning I can not click any other link.

However this happens only with Chrome and IE Edge. No issues with Firefox.

I installed the chrom web-developer addon http://chrispederick.com/work/web-developer/chrome/ and disabled all cookies.
When everything is disabled, it works like a charm.

I know this are not pretty much details. But can you help me? I even would like to invite you in a team viewer session to solve this problem. Of course i would pay you as well.

Need to get this done until tomorrow.

Thanks, 
Stansolo

If you can't click on the page you are making synchronous AJAX calls. It has nothing to do with cookies. Making synchronous calls has been deprecated (in FF since v30) you should not rely on that going forward.
