weird lines

While working on a responsive design, I now have weird lines on my MAIN size screen. Can anyone tell me how to get rid of them. They're driving me nuts...(short trip!)

Thanks, in advance,

Those red dotted lines are guidelines. There are two ways to make them go away. If you have screen rulers visible (Ctrl + L) right click on the ruler and select Delete All Guidelines.

Or if you want to keep the guidelines but not have them visible, in the Page and Layer Gallery, click the eye icon to the right of the Guides layer. The eye will turn red and the layer will be hidden.

Thank you so much Gary. I appreciate you sharing your knowledge!
