It happens every time I open a Setting Dialog or something like that in my System or even in all applications (eclipse etc.)
When I click on the check box like this one, it just doesn't show up that it was checked, instead it stays empty like unchecked. Its functional effect does take response, but I mean here the optical effect. I don't know yet whether if a check box, radio button were clicked/checked or not.
It's so weird and I have just no word to describe it properly :(
Thank you very much.
