Internet Explorer warning for TabSet.addTab()

[asadani]

I am using SmartClient 8.0 version

I have a tabset having 5 tabs and each tab has a Dynamic Form with more than 100 fields. The user of the application has an option to add more tabs with the forms by clicking a button. When the user clicks a the button to add a newTab we execute the following code

customTabSet.addTab
({
canClose:true, 
title:"newTab", 
pane:isc.DynamicForm.create({//form with 100+ fields}) })
);

The dynamic form has multiple 'section' items and the fields are spread across these section items. All these forms are linked to a single datasource and values manager.

After the 'customTabSet' has 7 tabs and the user adds a new Tab the Internet Explorer starts displaying the warning - 'A script on this page is taking....'.

Can you please suggest a way how this warning can be suppressed.

Thanks
