Alignment Gridlines No Longer Showing Up
It had always been for me that when in the Transform section and hovering my mouse over the sliders such as "vertical" and "horizontal," etc., gridlines would appear over my image, thus providing me a guide to how straight the objects in the image appear. All of the sudden, though, that no longer happens! I move my cursor there and just nothing happens. Any idea why and what to do about it? Thank you.
