John,
Have you installed update #429? This update seemed to solve the issue of those who could not access the Display Options.
From what I recall, the Display Options problem was related to (a) screen resolution (higher resolutions seemed to work ok) and (b) 16 bit graphics (32 bit graphic settings worked ok).
If you are not sure if #429 is installed, have a look at "Help | About Band In A Box", it should say 2016(429) for the version.
Update #429 can be downloaded from the below url and installed manually.
