I have been a huge fan of this theme for years. But I just did the update and now I can't get to all the options. When I open the preferences, they are all there for a fraction of a second, but then the top portion is gone and there's no way I can get to it! Please fix it! (MacBook Pro, Snowleopard, FF 12.0).
Thanks for your continued work on this.

ADDED: Thanks for your response. I did post a screenshot as you requested. I have not been able to check add-ons yet, but I will do that as well as soon as possible. I have no doubt this is an easy fix one way or another.

Thank you.

I have tested the theme with Snow Leopard and I have non problem.
Here are two screenshots :

Can you post screenshots to the support page please.
Have you try a clean profile with no other add-on?
