Thanks for your replies.
I have tried siria's skin, I mean the KM Skin, and it's a little too much for me. The klassic looks old is like Win98
I prefer the Phoenity (the small version of it) I have removed some buttons from it, like printer and zoom.
@guenter, I have downloaded the zip (which is small), but it requires too much cpu and HD disk space to unpack, I don't have space at this moment, maybe I will re-download it later after deleting some software from my PC.
