Selection in 3D view

Hi,

I use Unity 5.1.2p3 and Windows 7.

In editor, i have trouble with selection. I cannot selected a objet by clicking (in 3D view). It drives me crazy ! :rage:
Before, I had no problem

There is a solution hidden ? A option ?

Thanks

This is a known problem. Make sure you are not actually clicking on a UI, they get in the way. I have to exit Unity and restart it a few times a day because of this. Does it happen all the time for you?

I do not have UI in my scene. Its works after killed file named ā€œProjectSettings.assetā€.
But i think, this problem appear when the game is run in 3D view.

I’m having this same problem!
