I've just tested the tabs and there's no problem with clicking. Can you please try again? Maybe there's some JS errors somewhere else that could break the plugin's behavior?
I got it. The HTML is different because of the Meta Box Columns. You probably activated and used it on your localhost. Please try deactivating it first.
Anyway, I tested with the tabs and columns and they work pretty well together. Do you use the latest version of both plugins? Can you post your code here to test?
Oh, I see. It's MakiPlace's responsible to update the extensions for you. In the meantime, I've just added the Developer Bundle to your account and you can download the latest version of extensions. Please try and let me know how it goes.
