I am using Photoshop cc 2017.1.1. When using an adjustment layer such as curves, levels, hue & saturation, etc., selecting the targeted adjustment or eyedropper and clicking on the image causes the adjustment properties window to disappear. I can still use the pointer to make an adjustment but can not see how it is moving the curve or level or whatever. It does reflect in the image. I have to click on the adjustment layer icon to reopen the properties. Is there some way to make them stay open during the adjustments?
I figured it out. I had auto-collapse iconic panels checked. Found it by right clicking on the panel title bar.
