disable Konqueror mouse gestures (from the Control Center > Regional & Accessibility > Input Actions). if that doesn't work, disable horizontal scrolling for your trackpad (Control Center > Peripherals > Touch Pad). if you haven't done so, install KSynaptics in order to have a GUI for configuring your trackpad.
Thanks for the help. I ended up downloading the KSynaptics and installing it and now everything works perfect
I greatly apreciate your help with this.
