Bug in Photoshop CC. Rulers display inaccurately for large dimension files i.e. 30" x 36" 100dpi. They look fine at small sizes but when enlarged on screen to 50% or greater then the rulers are off buy 1/2" or sometimes they show repeated digits such as 3" and 3" next to each other. THIS WAS NOT A PROBLEM IN PREVIOUS VERSIONS OF PHOTOSHOP JUST CC. See attached screen cap if you let me attach files. India support wasted an hour and 42 minutes of of my time and created this case Number - 185-865-133 I am a 20 year user of Photoshop and THIS IS A BUG There are other complaining in the Forums and elsewhere of the same issue, Google it.. Mine is on a PC.
