Same issue.
Let's back up a bit, I might be misunderstanding the issue.
Your problem is that every so often, SMART will
take focus. What this means is that the window, no matter if it's minimized or in the background, will jump to the front. It will sit on top of every other window and demand your attention.
You mentioned CS:GO in your OP, I assume you're playing this in fullscreen.
Thusly, this issue probably manifests itself as SMART trading places with the game client possibly 1) causing CS:GO to minimize or 2) appearing on top of CS:GO.
After this happens, SMART is of course the active window. Any keyboard (or mouse, if SMART is disabled) input will go to SMART.
Is this the issue you're having?
