IE freezes randomly using jquery themes

I have been having a seemingly random issue where a .net web application randomly freezes for users. When this happens the user is forced to kill IE for being not respinsive.

All machines are windows 7 and this has been happening over various versions of IE 10 and 11. We use jquery themeroller in the app to allow users to customize appearance and this always happens with the eggplant theme. Possibly because over the years we have not upgraded it properly. With other themes it may happen for one user and of they go back in its fine. The server runs multiple other high usage web applications with no problems.so i believe it to be specific to some javascript condition in relatin to a selected theme although again this is not 100% reproducible except for eggplant theme.

When the user encounters and error the script is doing a few things
1. Creating a jquery modal window
2. Creating 3 tabs to navigate between data and ...
3. Creating an iframe within one of the tabs to load a page

I cannot paste the code but i know it is working except for these random freezing conditions. I didnt notice in the folder that we store themes, specifically for the eggplant theme there is an older jquery ui file for 1.7.2 i believe and thats it. All other themese have versions 1.7 2 as well as 1.10.2 but i still cant explain why this would freeze an IE window. Any ideas why themes may be freezing the window or possibly if its related to the dialog or iframe creation?



If the theme is not up to date, then expecting it to work with the latest browser may not be a reasonable expectation. I would suggest you install the latest version. If that does not fix it, then you need to as for support from where ever you obtained it. If there is no support then you would be best to look for an alternate theme, because trying to debug this kind of third party no support stuff, is an exercise in frustration.

Please post the following information:1. Server OS and .NET version (hopefully latest 4.5.1)
2. IE exact version number (Screenshot of about dialog)
3. When did you do this test?

Note: There has been windows updates that fixes some issues in the server and IE 10/11 that fixes some major issues over December 2014 and February 2015.



Server is windows 2008 r2 .net 3.5
IE version: 11.0.9600.17633
update versions: 11.0.16 (kb3021952)

All updates for Server and client are up to date. This has been a problem for a year now across different patches.

@COBOL i understand an update may be required but im not sure what the best method is. Different versions run different versions of jquery all pointing back to the same themeroller site. I assume that is how different jquery-ui versions got placed into each theme folder. Do i need to find the correct jquery-ui file for the theme for each version of jquery-ui being used and put them all in the theme folder?



Hi,
I ran into kind of this issue IE stalled / consuming 100% of one CPU core the last couple of months.
It was related to a jQuery / Javascript resizing an embedded iframe when the browser window ran in full mode AND the screen resolution has been Full HD (1920x1080).
Have not yet been able to really identify the issue nor fixing it.

The reason I asked about the versions is that one of my colleagues could not run some of our site features until the following patch was installed in the IE 11 computer:http://support.microsoft.com/kb/3025390

if further help needed:Q1. Are you running your target site in standard mode or compatible mode? (Please add a copy of your DEV tools showing the contents of emulation tab especially document mode and user agent)
Q2. Did you clear all temporary IE files before testing?
Q2. Could you consider @coboldinosaur suggestion to have only one version of jquery ui across the site.
Your plan should be:1. Remove 1.7 2 and upgrade any code that uses this old version to 1.10.2.
2. Test if it works.
3. If it does not, then get the latest jquery ui and test again.
