Hey Phil. Thanks for the note here. On the first point (the display issue), I've asked a dev to chime in directly. Should be a pretty straightforward CSS issue if I'm understanding it correctly.
As for the second, related to permissions: I was just unable to recreate this on my local install. What level of access do the affected users have? Are they Admins, Editors, Authors, Contributors? Or have you modified/created a custom role for this? If the latter we do have a known issue in the system with custom roles that should be fixed in 2.0.5. Please also let me know if you have any plugins installed that could be impacting/altering how roles interact with the site. We can try and troubleshoot from there.
