out memory - enormous loop - asp.net ajax framework

we're controlling .net 3.5 sp1.

recently, ie, the users started removing "out memory" errors once while. doesn't occur time. i managed replicate integrate times i found code, ajaxcontroltoolkit.common.common.js file, causing an enormous loop:
ajaxcontroltoolkit.textboxwrapper.registerclass('ajaxcontroltoolkit.textboxwrapper',
sys.ui.behavior);ajaxcontroltoolkit.textboxwrapper.validatorgetvalue =
function(id) {
var control = $get(id);if (control && control.ajaxcontroltoolkittextboxwrapper)
{
return control.ajaxcontroltoolkittextboxwrapper.get_value();}
return ajaxcontroltoolkit.textboxwrapper._originalvalidatorgetvalue(id);}

the final line (which calls _originalvalidatorgetvalue) fundamentally calls behind accurate duty over over since control.ajaxcontroltoolkittextboxwrapper undefined.

the duty tangible right above ajaxcontroltoolkit.textboxwrapper.get_wrapper(control) emanate coupling doesn't exist, nonetheless i don't feeling i wish changing horizon i'm wholly who's seen bug wild.

the bug does always occur. seems start initial url hallowed contains an ajax story point. open adult page play it, causing story points added, works fine. nonetheless copy-paste url another browser windows, problem.

therefore, speculation i am doing something wrong story control doesn't setup wrappers properly. even so, there appears an enormous loop there.

any ideas/clues?

i filled out bug news microsoft connect. while stuffing out contrast several scenarios, i beheld operative glorious locally nonetheless remotely. comparing production/development environment, i beheld combinescripts fake locally. deploying prolongation server seems have resolved issue.
