Hi Devs,
This is a really odd bug related to outside the game.
Basically sometimes (random as hell) after I've closed dayz my mouse will allow a single click to whatever (windows button, random open application, newly open application) but only a single click. Once the application is highlighted/brought to front, mouse clicks withing the selected app has no effect.
On the three separate computers that I've played dayz (32bit and 2 separate 64 bits systems) I've encountered this problem on several occasions.
Initially I assumed it was the old ass mouse I had but after replacing and still hitting the problem from time to time I knew it wasn't the mouse itself.
