MUI - question about grouping

[Comperio]

OK, I found my problem. (and a bonehead problem at that!)

I was using a default installoptions.ini which I then modified using a special function inside my install. I initially had the 2nd group disabled and then only enable it if I find user has option XYZ on their computer.

The problem was that when toggling the enabled flag, I failed to include the GROUP flag!
(D'OH!)
