I know how to attach Glossary mode into View page, based on setting here. I have tried to attach this mode into one of my block, but it does not seem to work. Is there a solution that work for block with Glossary mode?

I fixed by adding a View page(then I disable this) and that Glossary mode just work fine on block, except it will disappear once a letter is clicked. I found a solution about this issue on Drupal 6. Does anyone know how to fix this on Drupal 7?
