Collapsed interface panels
Hey
I do have a problem that is very annoying. Every time I launch the Illustrator, all the panels are collapsed. They are visible, but the content of them is hidden. I have to click on every group name to see it's content again. Selecting any other function from tool menu, hides the content again. Also the right menu is always changing the size, so it is very random how the items are displayed. I've tried to reser preferences, reintall program, create interface profiles, and so on. Nothing helps.
Any idea, how to make the interface always visible?

In addition I can say, that it does not matter if I am working on my or on predefined layout:
