# Selection in Edit Mode not working

I was doing a lot of different things in Blender recently and I could select verts with C, B and right mouse button. Now, it is not working anymore. Not even selecting edges or faces. Just the whole object by A.
I guess I must have pressed any key that locks it by accident.
I was doing some UV changes, some Mesh deformation and was tweaking things in texture paint mode. I cannot really say where it happened but somewhere later after the mesh changes were applied.
Hope anyone got a clue what to do.

EDIT: I was streaming with OBS again and it happened again! I closed and re-opened both programs a few times, selected different .blend files and the problem still occurs. Closed everything, re-started blender first. I then switched to xSplit and it appeared again...

Have no idea how this could help but here a picture explaination. Added a cube to the current file.

• It could be interesting to see if an error or a warning appears in the console. With Linux, start a terminal and type blender. On Windows, click the Toogle System console option in the Windows menu (or maybe in the Help menu). Add a screenshot of the console on your post. – Dominique Parisot Sep 1 '17 at 6:20
