Memory leakage with jQuery 1.6 and jQuery 1.8.16 on IE 7?

Description
Hi there,
I tested two blank pages on IE7
The first page
<head>
<script src="/jquery/1.6.2/jquery.min.js" type="text/javascript"></script> <script src="/jqueryui/1.8.16/jquery-ui.min.js" type="text/javascript"></script>
</head> <body> </body>
The second page
<head>
<script src="/jquery/1.4.2/jquery.min.js" type="text/javascript"></script> <script src="/jqueryui/1.8.16/jquery-ui.min.js" type="text/javascript"></script>
</head> <body> </body>
After each refreshing with F5, IExplore used 2 or 3 more megabytes memory with the first page. However it did not happen on the second page.
Does jQuery 1.6.2 bring memory leakage for jQuery UI library? It also happens on jQuery 1.5.1, 1.6.1.
Thanks
Limin

Hello, sorry for bad english.
I am in the same configuration ui 1.8.16 , Jquery 1.6.2 and IE7 . And have the same huge memory leak .
(I try with 1.8.x too)
4 MO !!!! at each refresh, with just adding reference to Jquery and UI script on my page!!!! i do nothing else!!!
Jquery UI is so wonderful ...
No idea why, but IF YOU WANT IT TO WORK follow these steps.
Download (with the custom download ) only the package that you need (I download only Dialog) and it works !
no memory leak.!
I test a little and the memory leak seems to appear when i have integrated the DatePicker (even if i don't use it! just refreshed my page).
Now, i can use the Dialog (seems to be ok for the rest but don't download the datePicker). I will try futher later to isolate the datePicker.
I hope that a developper will read my post to kill this ugly bug.
Bye

Hi,
I have the same problem. IE7 with memory leaks, after each refresh with F5.
The solution of excluding the datepicker from the UI is not working for me.
I've just test with jquery 1.6.1, 1.6.3 and 1.6.4 and with jquery-UI 1.8.13 & jquery-UI 1.8.16.
In my tests, the only way to avoid the memory leak is do not to include jquery-UI in the page.
Anyone can help?
Thanks.
Mike.

Hello,
I test this issue using jQuery 1.7.1 and jQuery-UI 1.8.17. The DatePicker still causes memory leak about 2MB in my situation.

Hello!
I have done a test with jQuery 1.7.1 and jQuery-UI 1.8.17.
From jQuery-UI 1.8.17 I have reverted the change #7256 that Peter talks about in the first comment above.
In this setup there seems to be NO memory leak at all in IE7.
The change in #7256 is to bind hover events (mouseout and mouseover) with 'delegate' instead of 'bind' on the Datepicker component. Also a global variable 'instActive' is added which is used in the 'delegate'.
Can the change from 'bind' to 'delegate' be the reason for the memory leak or can the global variable cause the trouble in some way?

After doing some tests, it seems that the memory leak started in jQuery UI 1.8.13. By reverting the changes in #7256, the memory leak disappears. The tests were done with jQuery 1.6.2. Can someone verify?
