Saving Page Content Sharepoint with IE8 cause annoying delay

This is very annoying problem when you are programming with IE8 and using sharepoint .We are working with custom layout pages coding and this problems occured and waste our valuable time.

Symptom

When navigating away from a publishing page that is in edit mode the browser displays “Saving Page Content…” in the status bar which can take up some time (about 15 sec)  to complete before asking for confirmation to not save the page.There were no such error with either IE7 or FireFox.

Cause

SBN_CallBackHandler() client function of SaveBeforeNavigationControl is not called as it supposed to. It looks like the implementation of XMLHttpRequest object in IE8 is somehow different from the previous release

Solution: There are three different solution

1) Change IE8 configuration parameter

Click -> tools -> Internet Options -> Advanced (tab)  and uncheck

Enable native XMLHTTP support (checked by default)

(This solution not worked with me but some blogs say thats ok )

3) Add javascript to your page:
