[CLIENT] X button not working

The general idea about this bug is: It prevents you, the player from closing the client via the X button, the X button located in the top right corner of the client.

How to reproduce:

1: Start client and log in.

2: Play a game of league of legends: Preferably using new draft champion pick.

3: finish game and press "HOME" button in the aftermath lobby.

4: Attempt to exit client using X button.

Note: Other buttons are working as intended. Is just X button that refuses to respond.

Though this bug happens, it happens whenever it wants to. I have been able to consistently close my client via the X button prior to today: DATE: 2016-10-15. TIME: 17:25 NOTE: Pressing right click on the league icon in the task bar does not work as no "quit this program" button comes up, as a matter of fact: Nothing comes up when right clicking the icon. This tells us that the only way for me right now to close the client is to use the task manager and kill the process and/or process tree.

Possible solution: Other users have stated that repairing the client will solve the issue, whether this is a temporary fix or a permanent one remains to be seen.

As of this time: No video or image exists to prove the existence of this bug. Image can be created but will show nothing. Possible showing of said bug has to be done by GIF and/or by video. None of which is doable for the original poster at this time due to different reasons
