switch left a right mouse button
 

I have just installed slackware 10 and after much frustration I got my wireless optical mouse/keyboard to work (Even scrolls) but.... the left and right mouse buttons have switched, essentially making it a left handed mouse, I probably changed something while trying to get it working but I cant workout how to change it back.

Any help would be appreciated.

Thanks

sorry, just worked it out, I was so busy trying to figure out xorg.config when I only needed to change it in KDE control panel.....I feel like a knob.
