Learning Skills Window Freezing?

Well I just stared DFO because I'm highly bored of MS now, I'm still grasping the basics but whenever I go to a skill teacher to get skills, the window just freezes/lags (I can't tell) and I can't even get any of the skills. When I close that window, the game flows just fine. I'm getting frustrated because I can't experiment with the available skills.

I'm playing a gunner if that makes a difference.

Relogging usually fixes it.

If relogging doesn't work at first, you can try restarting your computer and then relogging. I know I've had to do that a few times to get it working properly again.
