Suse Studio plays a great role and I thank you wholeheartedly. I made a short time ago a Linux system that is free to download from the web. Now I have set a new one, only that something does not seem more 'work as before. Any version I try to do it seems to have no more 'a window that contains it, but only the commands of his program. A window into Kde can 'be enlarged, reduced, closed, minimized, but now appears even more' command over the window that allows it. Also in the bottom panel of Kde does not appear more 'list of open windows, as if no program was running and I can not choose between multiple' windows open or minimized. There 's some with an installation program or library that allows you to fix it? Thank you and good evening to all.
