Game Mechanics: Clicking forces game to minimize

[Daymar]

It seems to be at random when in Full screen, anywhere I click whether it be a hotkey, another char, an items link etc. my entire game window is forcefully minimized to the desktops taskbar. Not only is it hellish annoying but it has even nearly gotten me killed a couple of times. I've tried decreasing my desktops resolution and closing out my vista sidebar but neither of those helped.
Does anybody else have this issue?? Any help would be much appreciated.
