I've had a look in my WBO folder and I can see there's 2 for my skin, one that's got the .WBO extension, and one that's got a .WBO7 extension.Would having the two of these be causing the behaviour I'm experiencing?
As someone mentioned this happens after logging in from the lock screen, I guess I should mention that this happens to me if I play some games (Such as Battlefield 4), which is what was leading me to thinking it's some sort of Windows Compatibility mode problem, although I could be way off mark there.
As for the WBO files, should I associate them with the WB7 exe?
