From forum user zknewbie1's post ( http://www.zkoss.org/forum/listComment/17912 ):
Hi, I run the following test code on IE8. It takes a long time to run and finally raise the errors below. It runs fine on Chrome and Firefox. Any insight is greatly appreciated. Thanks.
1st Error message (Windows IE popup window):
Stop running this script? A Script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer might become unresponsive
2nd Error message (an orange javascript popup window):
Redraw Close
Failed to process

I then opened the detailed javascript error, and it says:
