I am now having this VERY same deselecting problem. Was there ever a resolution? If so, what was the fix? Somebody please tell me!!!
For the past six months or so I've had the problem of having my active window deselect itself many time during a session...as often as every ten seconds or so. I have Windows 7 Ultimate 64 bit installed on a Dell Xps 15z-i7.
I have read most of the windows forum suggestions on this topic, and none have work for more than a week or two. I have run ARO software checks and Advanced System Care 6 Pro. No help.
Any ideas?
I updated my Nvidia software...no help.
