I am not sure what happened but my horizontal and vertical grid lines in Lightroom 6 crop tool are now at a 45 degree angle. Originally when I wanted to crop a photo and clicked on the crop tool horizontal and vertical grid lines would appear, the lines still appear but they are now on a 45 degree angle. I have tried everything I can think of to get them straight again but to no avail. I am sure I did something to get them crooked but here again I don't know what it was. Does anyone out there have any idea how to get them straight again?
Hit to "o" key a few times in the crop tool to cycle through the the overlay patterns.
Thank you very much for your quick and correct reply. For some reason unknown to me I must have been "o"verly excited about the "o" key.
