Hi all.  I have posted this question in several places and read hundreds of posts on the subject, yet I can not seem to find my solution. 
Problem is how my screen is functioning between IE 6 and IE 7 on a Windows 2000 server. It seems that not only are my javascript events firing in different order, but my IE 7 page freezes after selecting an item in a div cbo box. The Div closes and the screen hangs. Putting alerts in the javascript, I can see what is firing and likewise, the alerts prevent the screen from firing.
I did not write the original code. I am hoping someone may have had similar issues to which they could offer some suggestions or a solution.
