I took turns turning off all addons until I figured out which were having issues. When I have questhelper enabled, the "Addon Preferences" Cartographer tab doesn't allow me to easily click on a link. However, if I click over & over again, eventually an option will be chosen.

This is always the case when I have both installed, and is always working when I've turned off questhelper.

For now, I'll turn off questhelper when I want to use Cartographer_routes for instance, but I can't tell if it's a Questhelper problem or Cartographer. Or really it's both's problems, since it causes a conflict :)

I use WowAceUpdater and have the latest version of Cartographer, and have downloaded the latest version of questhelper.

Questhelper:
Development Version: 0.44.17-gf3f3830

Cartographer:
