Evidently there are known issues with IE and there are limitations on the number of contacts that you can enter at any one time before the site kicks you off, so if you have multiple contacts to enter you may be better off to import from Excel rather than lose a bunch of time...
Thanks for posting, I am sorry for the frustration that working in IE has caused. What version of IE are you working in? Constant Contact is compatabile with the recent versions of IE but we no longer support IE 8.
When you are entering contacts can you tell me more about how you are adding them to the account? Are you typing them in with contact details or are you pasting in multiple contacts at once?
