Popup Applet (X Confirmation Prompt) , close and save workaround

New security features in .10 'clicking X on pop-up/mvg causes an additional security popup 'ok lose changes' ' is not a feasible option for my client.   I need a way to close the popup applet without this additional step.  I need to close the applet with the 'Save' or 'Ok' button HOWEVER prior to closing I need to execute code to write to another bc.   I confirmed the writerecord event is being triggered at browser, then bc  however if I add the this.invokemethod("CloseApplet") at bc server script it does nothing.  If I add the logic to browser the applet closes
