[support] Nice Menus - two quick questions

I'm setting up the Nice_Menus block and I have a couple of questions. 1) Although I have "Block Title" set to "<none>", the title is still displaying - how do I remove this? I seem to have clicked on something in admin somewhere an am unable to find what I did and how to unset the block display. 2) Although I have the Nice_Menus block visibility set to everybody ("If you select no roles, the block will be visible to all users"), it is currently only visible to logged in users. How do I remedy this? Thanks,Marc
