KDE Screen divided into 4 vertical screens

Hi, I just installed Suse 8.1 on a PC for the first time. I've been specially amazed by the KDE graphic interface. However I'm having a problem with my screen. After searching the internet for days and days I couldn't find any helpful information. The problem is as follows: The screen is divided in 4 different vertical screens. The left screen is about one half of the entire display area, the other half is divided into 3 identical vertical screens. The right part of the bigger screen is repeated in all the other 3 screens identically. A friend of mine said he's seen this already but has no clue as what's the reasons or how to correct it. Would anybody have any clue or hint? Thanks, Mamadou Cisse Alatto Technologies www.alatto.com.
