Win 8.1. Unity Shuts Down Automatically when asset store window is open and I either click the Left Mouse Button or use the scroll-wheel.

I have restarted my computer and have installed latest GFX Drivers and updates. I’m also using the stock Windows 8.1 Firewall and windows defender( Security Essentials).

I have tried to duplicate this and it happens 100% of the time.

Why is this happening? It’s absolutely kicking my ass because at random times Unity just shuts down.
