Set the progm to be NULL so that we won't call mb_progm_abort when we call it at the next time. This will fix the crash issue of the dynamic. However, the dynamic is still crash sometimes if we click the button quickly. It looks like it crashes in the refresh. We need to future figure out the issue.
