No worries. The security was isoloated solely to that particular button. The security on the other buttons on the screen worked as I had configured it.
The security error message I was getting was incorrectly indicating the user was not in the correct role even though the user was in the proper (Sales) role.
Simply creating a new button and setting the security the way I needed it, then copying the previous button's actions over did the trick.
Weird. Luckily it was an easy fix.
Thx
