You need to handle the FrmDrawForm() yourself, and therefore return true so
that PalmOS doesn't do it afterwards. In other words, frmUpdateEvent is
called prior to the normal handler which does a FrmDrawForm() which will
erase the screen first.
case frmUpdateEvent:
frm = FrmGetActiveForm();
FrmDrawForm(frm);
DisplayFooter(true); /* my routine that draws stuff */
handled = true;
break;
