Minor problem. Have to exit and restart MP3Tag for changes in Options -> Genres to take affect.
This is not a bug, but a "limitation" of the feature.
oops. my bad.
Missed that section in the help.
Thanks for the hint anyway.
I've improved my coding skills since I've written that code and I'll change it to the next release
Bug = Not according to specification
Feature = According to spec but the spec is wrong
Marketting Feature = A documented feature
This will make the interface more intuitive. I guessed that the drop down list was populated at init.
