.Map :: MoHAA Mapping

Hi guys.

Im messing with my very 1st map. Ive run into troubles many times while moving the camera only and not trying to select any brushes or terrain. Ive noticed that one or more objects simply change textures when im holding down ctrl and right click on the 3d view to move the camera up or down.

Is there a way to prevent this?

In preferances, change to three button mouse. Right clicking with two button mouse set, causes the texture under the pointer to be copied to the selected brush or face. With three button mouse set, it is the center wheel button that does that.

Thanks!
