You should be able to go into the Workflow Thresholds configuration section and set the permissions for the NOTES section specifically.  It will let you modify based on the role and action.
Take a look to see if you've done this or not.  Also - be sure that you are not overriding any of the configuration settings related to the bug notes - in your config_inc.php.  These will override the settings in the screen.
I hope this is helpful.

Subject: [mantisbt-help] Adding note without changing state
Date: Friday, October 2, 2009, 9:07 AM

      Developers can only write notes when they are changing the state of a
bug to solved. May someone tell me what to change this and allow them to
write note without changing the state? I have given them permission to add
notes, but it seems that did not work at all.
