Problem with Page & Layer Gallery

[digitalphaser]

Hello,
I already asked this question without answer. Now I want to ask the developers.

Problem:

The active layers are non-editable.
I can open active layer. All objects of layer are editable too. But the SOLO, VISIBLE and EDIT symbols are gray and do not respond to mouse clicks.





I tried to repair with CD, but result is same.
What could it be?

If only reinstallation will help then should I deactivate program?
