I will say this.
The crashing started out less frequent than last season.
As time went on it became more frequent.
Now its back to every five minutes.
It has to do with Explorer.exe and the game constantly vying for attention.
Click in game and desktop will flash for a hair of a second.
This is creating all kinds of problems and has been by the lack of an exclusive fullscreen mode.
I have suffered through, around 40 crashes today.
Cant do it anymore this season.
Shame because i was actually having fun and had a build that was uncommon yet recking.
That is like 3 season now because of this issue.
Take care blizzard.
