infragistics web data tree ie script error

Question

Hello,

I work with infragistigs (NetAdvantage 2010.2) and I have a data tree on my page. But with the Internet Explorer (6, 8) the following error message is indicated:

"The script break

A script on this page causes browser delays. Another version of the script may cause that the computer stops responding."

Only in the intert explorer and if you click yes, the same message comes again. Click yes again and you get on the page. But nothing is saved in the session! This is every time, no difference between checked boxes or unchecked boxes.

The data tree works with a 2065 lines big xml file! Can it be that this is too much to charge for IE?

EDIT: Yes it is too much! But can I fix it?

Thanks for help!

Best regards, j
