>> Hi,

>> First page I constructed with Dojo:

>>
>> Second page I constructed with Dojo:
>> http://hkpcug.homeftp.net/~francium/dojo-0.4.1-ajax/dojo_leak_widget.html
>>
>> Notice that the links might be very slow or even unreachable, because my

>> I've attached the .html file to my post as well.
>>
>> In both examples, clicking "Creating xxx widgets" and then "Destroy All"
>> repeatedly in IE6 or IE7 would lead to the vmsizes of both browsers (as
>> observed from Window's Task Manager) increase rapidly. How can I correct
>> this problem? And could anyone kindly point to the reason why is it
