Tab’s problem

Hi,
I have a big problem with tabs. I use this since several months, but after the last update I can’t use them.

The problem : When I want to modificate a word, a space or whatever, my tab doesn’t work anymore. The name of each file-tab appears but you can’t click on it !

Observation :
It appears that there is interferences between “Tab” and “Block Wrapper”. When I use tab in a block wrapper, it doesn’t work, when I create it out of a wrapper, it works (if I don’t modificate it anymore after !). This “block wrapper” is part of qubely, not another plugin.

Please, can you look at rhe problem quickly, my site use this tab on every page, I choose qubely specially for this tool.
