Cannot select GUI buttons in Scene view -- Multiple versions of Unity and projectd

This seems like it’s completely isolated on my PC but I cannot select GUI elements in the scene view using the GUI tool (2d rectangle tool, what’ever it’s called. Keyboard shortcut T)

I’ve tried it across multiple reboots. I’ve tried it in multiple projects/scene. I’ve tried it in 5.2.2, 5.3.5 and 5.3.4.

button selection DOES work in 4.6. But not in those others.

I watched my coworker successfully select buttons in the same project on his machine. But mine isn’t selecting.

I can select them in the Hierarchy view, and once selected there I can edit them in the scene view (resize, move). And I can deselect them by clicking outside of a gui element. I just can’t select them if they’re not selected already.

ANY suggestions? I’d think it’s registry/preferences thing but it happened across 2 different installs of Unity (on the same machine.)

this is driving me nuts.

are the UI buttons at the Same Depth? :stuck_out_tongue:

i’m not very familiar with unityUI, but there has to be a way to check for the world or global position of the selected image somewhere.
