Wrongly enabled buttons in apps/prefs

[diver]

There are several apps/prefs which enable some buttons on the first start, when i didn't change anything. Here is this list:

Fonts - Default Keyboard - Default Keymap - Revert, Use Mouse - Default Screen - Default, Revert, Apply Scroll Bar - Default Virtual memory - Default

Also, when you start Sounds, you could see how butons becomes disabled Sounds - Play, Stop.
