After playing Minecraft for Win 10 on my Windows 10 PC, my touchpad is not functionnal.

Before playing, it working, but after nothing...

I don't know that was Minecraft made that bug, so I search how to deblock my touchpad on Internet, I found something, but always infunctionnal. 

After, I understand that bug can be made by Minecraft Windows 10 edition, and yes.

I made the Windows 10 Fall Creator Update for my PC, and my touchpad was functionnal !

But, after when I play Minecraft, my touchpad was not functionnal.

For deblock this bug I need to restart my PC, and it take lot of time...

Please correct this bug, I'd like to don't to restart my PC because it's really painful.

Thanks.
