Adding hyperlink on a button when clicked

We are using V 7.6.  I am opening a new metastorm process/form through a SharePoint link.  When I click on the CANCEL button within the Metastorm form, a message is displayed asking ; "The web page you are viewing is trying to close the window. Do you want to close the window?  Yes or No."  When I click YES, the entire I.E. closes.  When I click NO, I get a blank screen that is hung.  Is there a way to add a custom url links to buttons that will place me back to the original web page when the CANCEL and/or SUBMIT button is clicked?
