Sys is undefined with IE - Only if you have Advanced options - Disable script debugging (intern Explorer) turned on!

Hello all,

i have the following issue, if you take the bottom code and use it in a aspx page.(i put it at the bottom of a large page).

And you go to the advanced options in your internet browser - with the option "Disable script debugging (internet explorer)" turned ON ! i get the famous Sys is not defined error. However if dont use this option, and opt for wanting to enable script debugging (so i can figger out why i get the error) no such error occurs. All the other code also seems to work as intended after this.

 if (Sys && Sys.WebForms && Sys.WebForms.PageRequestManager && Sys.WebForms.PageRequestManager.getInstance) {

    Sys.WebForms.PageRequestManager.getInstance().add_endRequest(doPartialPostbackFunctions);
}

Is this working as intended or am i missing something in my debugging skills? Or perhaps it is a known issue? (couldnt find anything related with the option about debugging)

Thanks, Vince
