Default accept / cancel form buttons!!!!!

Question

Ok, I am hoping this is an easy one. I have a form with 7 buttons on it. The buttons perform various functions such as loading other forms, etc. I purposely DO NOT want to have a default accept / cancel button associated with this form at any time. I am noticing that when you click any of the buttons, the button last clicked becomes the default "accept" button for the form. How can I stop this behavior??? Please help. Bob
