I just noticed the sprite selector wasn't working in my project when clicking on "Sprite" in the UISpriteInspector (in 2017.1.3). I looked back through source control and while I have made quite a few changes to Ngui 3.11.4 core, none had anything to do with this and this was working just a few weeks ago when I refactored the look of my chat window. Then I changed to a fresh project with just Ngui installed and the same behaviour was exhibited there.
The window is clearly displaying - OnGui is being run ok for the sprite selector - but no window displays. The Unity title bar does deactivate though - clearly it thinks the window is there, but it is just not being drawn.
Anyone know what the fix here is? If it is upgrade to a newer version of unity or wait for unity to fix it, that would be fine. But I am welcome to any known fixes too.
