Hello Everyone, Here's the situation: two iSeries boxes - Dev and Prod both V5R4M0 We're using AJAX to dynamically load content using a tabbed based navigation using this code: http://www.dynamicdrive.com/dynamicindex17/ajaxtabscontent/index.htm We have no issues loading information on our Dev box.  There's definitely less information to be loaded here, but, we have a test environment on out Prod box that mimics our Dev box.  The Prod test environment isn't working correctly either. It seems to happen only for some users, even though they go into the exact same page.  (We tried going in as QSECOFR with full access and it gets the issue). Here's an example situation: A user logs in and gets a list of information. They can use the tabs to filter that information bases on a status: completed, incomplete, etc... As you tab through the different statuses, the AJAX calls code that grabs that information and stores it in our container. Sometimes when you click a tab, IE 8 crashes completely.  I don't receive any javascript errors or code errors in the language we use (NET.DATA). This doesn't happen on our Dev box.   Are there any settings I can compare on our boxes that will give us an idea about what's different? If you need more information, let me know. I know this entire post was a little wordy and confusing.  If you saw our situation, you'd be just confused as us. Thanks, Dave
