I have a very strange problem that I never encountered and which I cannot solve in any way. I have been using JQuery a lot in the past years and I never encountered the issue which I will be describing.

Basically I am seeing that when the page does not load completely (because I would be loading everything asynchronously) and I try to refresh a Page or click an HREF link I get an undefined error. Sometimes I the undefined dialog box is shown once, sometimes more than once. However when I try to debug using Firefox, Chrome etc I do not get the actual error. Thus I do not get the $ undefined error and I cannot debug it in any way. 

I am loading the jquery in the head tag. Even when I tried to do it after the body the same issue occurred.
