I am using a modal popup that controls some of my navigation links. They all worked fine until I created a contact form as one of the popups. If I submit the form, the rest of the navigation continues to work. However, if I close the popup using the CancelControlId, the rest of the navigation does not work. I have tried to set up a OnCancelScript, but nothing seems to work. Any insight would be much appreciated.

Found the answer: it is the validation in the link buttons that cause the problem. setting the validation to false solves the problem.
