I've got a very difficult bug to spot and I wish someone could help me out here, please. What I've got going is a chatroom application using ajax, php, and mysql. Well the chatroom works fine but there seems to be a weird bug when I run the program in IE. there is a link on the page (same as the chatroom page) and it looks something like this: <a href="javascript:;" onclick="doSomething(divID)">click here</a> Code (markup): when I click on the link, some of the other contents of the page disappear for 1 second and reappears. I have never seen this type of behavior before. I am so far into the program that my mind is going round and round and I really have no clue what is causing this problem..all other browsers - FF, safari, opera works fine. Can someone please help me figure this out?
