Abstract
We prove that thick category associated to a semi-simple complex finite dimensional Lie algebra is extension full in the category of all modules. We also prove the weak Alexandru conjecture both for regular blocks of thick category and the associated categories of Harish-Chandra bimodules, but disprove it for singular blocks.
